    APPEL, Justice.
    While accompanying kindergarten students on a field trip to a
    dairy farm, a chaperone was injured when she fell through a hole in the
    floor of a hayloft. The chaperone filed a negligence suit against the dairy
    farm’s owners. The district court granted summary judgment in favor of
    the owners on the basis that Iowa’s recreational use statute barred the
    chaperone’s claims.     The court of appeals affirmed on the issue of
    whether recreational use immunity extended to the defendants as
    landowners, but determined the chaperone could still maintain a suit
    against the defendants as tour guides.
    For the reasons that follow, we conclude the landowners may not
    avail themselves of the limited protections of the recreational use statute
    because the chaperone was not engaged in a recreational purpose within
    the scope of the statute. We further conclude, however, that the plaintiff
    has not raised a material issue of triable fact as to whether the
    landowners willfully or maliciously failed to guard or warn against the
    presence of the hole. Accordingly, we vacate the decision of the court of
    appeals, reverse the judgment of the district court, and remand the case
    for further proceedings.
    I. Factual and Procedural Background.
    A reasonable fact finder viewing the summary judgment record in
    the light most favorable to Kimberly Ann Sallee, the nonmoving party,
    could find the following facts. Matthew and Diana Stewart own a dairy
    farm in Fayette County. Although the Stewarts do not routinely open
    their farm to the public, classes or individuals wishing to view the farm
    can schedule a visit.      These groups are always accompanied by a
    member of the Stewart family. If visitors arrive at the farm without a
    4
    scheduled appointment, they are only permitted to tour the farm if
    accompanied by the Stewarts.1
    The kindergarteners from the Sacred Heart School have been
    annual visitors for a number of years. During their visit, the students
    learn about the typical day on a farm.                    The students are usually
    chaperoned by their teacher, a few parents, and at least one member of
    the Stewart family. The Stewarts do not permit the students to go into
    cattle pens or other places where the Stewarts believe the students might
    be in danger.
    On May 18, 2010, Sallee accompanied her daughter’s Sacred Heart
    kindergarten class on a tour of the Stewarts’ farm. As with other visits to
    the farm, the field trip was scheduled in advance.                        The Stewarts
    accompanied the students during their visit and set up three stations for
    the students. At one station, the students rode a horse in a round pen.
    At another, the students could feed a calf with a bottle of milk. At the
    third station, the students could view a tractor. Matthew supervised the
    entire process, and adults were positioned at each station. Once they
    had rotated through each station, the students saw several cows and a
    bull.    The Stewarts then guided the group to the barn to allow the
    students to play in the hayloft.
    Matthew asked Sallee and another chaperone to climb into the
    hayloft ahead of the students so that they could assist the students at
    the top of the ladder.            After Sallee looked at the ladder, Matthew
    reassured her it was stable enough to support her weight.                        Sallee
    followed the other chaperone up the ladder and into the hayloft.                   The
    children, another chaperone, the teacher, and Matthew followed.
    1There   is no indication the Stewarts posted “No Trespassing” signs.
    5
    Matthew advised Sallee to keep the students away from the hole in the
    floor where the ladder was located and warned the students not to climb
    too high on the bales of hay piled to one side of the loft. While in the
    hayloft, the children ran around and climbed on the hay bales.
    The Stewarts never advised Sallee as to the presence of several hay
    drops, rectangular holes in the floor of the hayloft through which hay can
    be thrown to the animals below. Ordinarily, the Stewarts stack bales of
    hay across the holes when they are not in use to insulate the lower part
    of the barn. Prior to the class’s arrival, Matthew inspected the hayloft
    and stood on the bales of hay covering the holes to make sure they would
    support his weight. However, while Sallee was standing on top of a bale
    covering one of the holes, the bale gave way. Sallee fell through the hole,
    breaking her wrist and leg.
    Sallee filed suit against the Stewarts, alleging their negligence
    caused her injuries. The Stewarts asserted as an affirmative defense that
    Iowa Code chapter 461C (2009), Iowa’s recreational use statute, shielded
    them from liability.   The Stewarts later moved for summary judgment
    based on the recreational use statute.     In resistance to the Stewarts’
    motion, Sallee argued the recreational use statute does not apply as a
    matter of law because the dairy farm, barn, and hayloft did not fall under
    the definition of “land” in the statute, the farm was not available to the
    public, the tour of the farm was not a “recreational purpose” within the
    meaning of the statute, and Sallee, as a chaperone, was not engaged in a
    recreational purpose. In the alternative, Sallee argued that the Stewarts
    willfully failed to guard or warn against the presence of the hay drop and
    that the Stewarts were liable not as owners of the property, but rather as
    tour guides.
    6
    The district court concluded the recreational use statute barred
    Sallee’s claim.     The court reasoned that the Stewarts farm was land
    within the meaning of the statute. It also found that, while on the farm,
    the students engaged in horseback riding and nature study, defining
    terms of “recreational purpose.”     Thus, it concluded that Sallee was a
    recreational user because she was “a chaperone of children’s activities,
    which included horseback riding, nature study, and play in the Stewarts’
    hayloft.”     Finally, the court found that the Stewarts had not willfully
    failed to guard or warn against the hay drop and that they had not acted
    recklessly.
    Sallee appealed, and we transferred the case to the court of
    appeals.      A majority agreed with the district court that the Stewarts’
    property was covered by the recreational use statute. It also found that
    Sallee was engaged in a recreational purpose. It reasoned that, based on
    the language of the statute, the legislature intended an expansive
    definition of “recreational purpose” which encompassed Sallee’s role as a
    chaperone because the students had engaged in horseback riding,
    nature study, and play during their visit to the farm. It also determined
    the Stewarts had not willfully or maliciously failed to guard or warn
    against a dangerous condition, use, structure, or activity. However, the
    majority found that recreational use immunity did not extend to the
    Stewarts “once they undertook responsibility for guiding the field trip
    attendees.” One judge on the panel dissented from the majority’s holding
    on the premises liability issue on the grounds that Sallee was not
    engaged in any recreational purpose under the statute because she was
    present to ensure the proper behavior of the students as a chaperone,
    not to engage in any recreational activity.
    We granted the Stewarts’ application for further review.
    7
    II. Standard of Review.
    We review the district court’s grant of summary judgment for
    correction of errors at law. Ranes v. Adams Labs., Inc., 
    778 N.W.2d 677
    ,
    685 (Iowa 2010).      Summary judgment is only appropriate when the
    record demonstrates “that there is no genuine issue as to any material
    fact and that the moving party is entitled to a judgment as a matter of
    law.”   Iowa R. Civ. P. 1.981(3).    “An issue is ‘material’ only when the
    dispute is over facts that might affect the outcome of the suit, given the
    applicable governing law.”     Junkins v. Branstad, 
    421 N.W.2d 130
    , 132
    (Iowa 1988). The burden is on the moving party to demonstrate that it is
    entitled to judgment as a matter of law. Clinkscales v. Nelson Sec., Inc.,
    
    697 N.W.2d 836
    , 841 (Iowa 2005).          We view the evidence in the light
    most favorable to the nonmoving party. Id.
    III. Background of Recreational Use Statutes.
    A. Development of Recreational Use Statutes.
    1. Conflicting interests of public safety and increased access to the
    Great Outdoors. At common law, the extent of a landlord’s duty to an
    individual injured after entering the land typically depended upon the
    injured party’s status as a trespasser, licensee, or invitee.      Koenig v.
    Koenig, 
    766 N.W.2d 635
    , 638 (Iowa 2009). The duty owed to a trespasser
    was generally limited to avoiding willfully or wantonly careless conduct;
    the duty owed to a licensee generally included refraining from willful or
    wanton conduct as well as a duty to warn of hazardous conditions; and
    the duty owed to an invitee generally included the duties owed to a
    licensee as well as duties to make the premises safe, to inspect the
    property for dangerous conditions, and to either repair or warn the
    invitee of such conditions. See W.L. Church, Private Lands and Public
    Recreation: A Report and Proposed New Model Act on Access, Liability and
    8
    Trespass 7–8 (1979) [hereinafter Church].        We have recognized these
    distinctions in our cases. See Koenig, 766 N.W.2d at 638; Sheets v. Ritt,
    Ritt & Ritt, Inc., 
    581 N.W.2d 602
    , 604 (Iowa 1998), abrogated on other
    grounds by Koenig, 766 N.W.2d at 643–45.           Potential liability was a
    disincentive for landowners to make their lands available to the public
    for recreational purposes.
    Following World War II, the demand for access to land for outdoor
    recreational purposes was increasing, but at the same time the amount
    of land for such purposes was decreasing as the public also demanded
    more infrastructure, such as “subdivisions, industrial sites, highways,
    schools,   and   airports.”    Outdoor    Recreation    Resources    Review
    Commission, Outdoor Recreation for America: A Report to the President
    and to the Congress by the Outdoor Recreation Resources Review
    Commission 1 (1962) [hereinafter ORRRC Report]. Further, as Americans
    became increasingly obese, public health advocates sought to expand the
    recreational opportunities available to Americans. See Michael S. Carroll
    et al., Recreational User Statutes and Landowner Immunity: A Comparison
    of State Legislation, 17 J. Legal Aspects of Sport 163, 163, 178 (2007)
    [hereinafter Carroll].   Legislatures responded by considering measures
    that would lessen somewhat the exposure of landowners to liability to
    persons entering their land for recreational purposes while still providing
    a degree of protection to the public.           See Comment, Wisconsin’s
    Recreational Use Statute: A Critical Analysis, 66 Marq. L. Rev. 312, 316
    (1983) [hereinafter Wisconsin’s Recreational Use Statute] (describing
    recreational use statutes as a “ ‘tradeoff’ whereby the landowner is
    relieved of certain tort liabilities when he gratuitously allows members of
    the public recreational access to his land”).
    9
    The literature describing and supporting modification of the
    common law to promote public recreational use on private land generally
    focuses on the needs of sportspersons engaged in hunting, fishing,
    hiking, and similar activities taking place in the Great Outdoors. See,
    e.g., Tommy L. Brown, Analysis of Limited Liability Recreation Use
    Statutes in the Northern Forest States 1 (Cornell Univ. Dep’t of Natural
    Res., October 2006), available at http://www.dnr.cornell.edu/hdru
    (noting that in addition to hunting and fishing “access to private lands
    has   become   increasingly   important   .   .   .   for   trails   for   hiking,
    snowmobiling, cross-country skiing, and use of all terrain vehicles”);
    John D. Copeland, Recreational Access to Private Lands: Liability
    Problems and Solutions 6      (Nat’l Agricultural Law Ctr., 2d ed. 1998)
    [hereinafter Copeland] (“An increasingly urbanized population is in need
    of wider access to lands providing wilderness or rural experiences.”);
    Ronald A. Kaiser & Brett A. Wright, Liability and Immunity: A National
    Assessment of Landowner Risk for Recreational Injuries iii (USDA Soil
    Conservation Serv. 1992) (“Vast increases in the use of public lands for
    recreational use have led to more frequent requests by the recreating
    public to gain access to private, rural lands for purposes of hunting,
    fishing, and other outdoor activities.”); Debra Wolf Goldstein, The
    Recreation Use of Land and Water Act: Lory v. City of Philadelphia, 35
    Duq. L. Rev. 783, 785 (1997) (pointing out that state recreational use
    laws provide a means of “making open space lands available to the
    public” in place of the government’s acquisition of lands); Wisconsin’s
    Recreational Use Statute, 66 Marq. L. Rev. at 315 (noting that as of 1983,
    forty-three states had adopted recreational use statutes to “limit the
    liability of landowners whose lands are used for recreational purposes
    such as hunting, fishing and sightseeing”); Note, Torts—Statutes—
    10
    Liability of Landowner to Persons Entering for Recreational Purposes,
    
    1964 Wis. L
    . Rev. 705, 705 (1964) [hereinafter Liability of Landowner to
    Persons Entering for Recreational Purposes] (noting that Wisconsin was
    the tenth state to adopt a statute aimed at “encouraging public
    recreational use of privately owned forest and farm lands”).
    2. Early recreational use statutes in the Midwest.          Michigan and
    Wisconsin were the first Midwestern states to enact recreational use
    statutes.2 See Liability of Landowner to Persons Entering for Recreational
    Purposes, 
    1964 Wis. L
    . Rev. at 705 & n.2. These statutes were aimed at
    promoting traditional outdoor recreation and limiting the liability of
    landowners who opened their lands for public use.                 For example,
    Michigan’s recreational use statute as enacted in 1953 stated,
    “No cause of action shall arise for injuries to any
    person who is on the lands of another without paying to
    such other a valuable consideration for the purpose of
    fishing, hunting or trapping, with or without permission,
    against the owner, tenant or lessee of said premises unless
    the injuries were caused by the gross negligence or wilful
    and wanton misconduct of the owner, tenant or lessee.”
    Wymer v. Homes, 
    412 N.W.2d 213
    , 217 (Mich. 1987) (quoting 1953 Mich.
    Pub. Acts 201 (emphasis added)), overruled by Neal v. Wilkes, 
    685 N.W.2d 648
     (Mich. 2004). Although the Michigan legislation as originally
    proposed in 1953 applied only to hunting, the Michigan legislature
    amended it to include fishing and trapping before passage later that year.
    See id. The Michigan statute was further amended in 1964 to include
    “camping, hiking, sightseeing, or other similar outdoor recreational use.”
    Id.
    2The states that had enacted recreational use statutes by 1964 were Maine,
    Michigan, Minnesota, New Hampshire, New York, Ohio, Pennsylvania, Tennessee,
    Virginia, and Wisconsin. Note, Torts—Statutes—Liability of Landowner to Persons
    Entering for Recreational Purposes, 
    1964 Wis. L
    . Rev. 705, 705 & n.2 (1964).
    11
    Wisconsin enacted its recreational use statute in 1963. The act
    was originally promoted by owners of timberlands who wanted to invite
    deer hunters onto their lands to prevent damage brought about by
    excessive deer herds, but who feared tort liability stemming from injuries
    suffered by the invitees. Goodson v. City of Racine, 
    213 N.W.2d 16
    , 18–
    19 (Wis. 1973); see also Liability of Landowner to Persons Entering for
    Recreational Purposes, 
    1964 Wis. L
    . Rev. at 709. The Wisconsin statute
    applied to “hunting, fishing, trapping, camping, hiking, berry picking,
    water sports, sightseeing, or recreational purposes.” Wis. Stat. § 29.68
    (1963).
    The benefit of these early recreational use statutes was recognized
    by the Outdoor Recreation Resources Review Commission (ORRRC) in its
    report published in 1962. Established by Congress in 1958, the ORRRC
    conducted an extensive nationwide study of outdoor recreation, which
    resulted in a report entitled Outdoor Recreation for America: A Report to
    the President and to the Congress. See ORRRC Report at 1–2. The report
    declares, “This report is a study of outdoor recreation in America—its
    history, its place in current American life, and its future. Id. at 1. The
    ORRRC’s report indicated that as of 1962 Americans sought a variety of
    outdoor   pursuits,   including     pleasure   driving,   walking,   boating,
    swimming, fishing, bicycling, sightseeing, skiing, mountain climbing,
    picnicking, and skindiving.       Id. at 25–26.   It estimated that three-
    quarters of Americans would live in urban areas by the year 2000 and
    noted that urban dwellers would have the greatest need for (and least
    supply of) outdoor recreation facilities. Id. at 3. More importantly, the
    ORRRC predicted the nation’s demand for outdoor recreation resources
    would nearly triple by the turn of the century. Id. at 32. The ORRRC
    12
    made a number of recommendations for the federal and state
    governments, one of which was the development of a national outdoor
    recreation policy and the creation of a Bureau of Outdoor Recreation
    within the Department of the Interior to provide leadership in meeting
    the demands of outdoor recreation.            Id. at 6–7, 121–26.       The ORRRC
    suggested the states “encourage the public use of private lands by taking
    the lead in working out such arrangements as leases for hunting and
    fishing, scenic easements, and providing protection for landowners who
    allow the public to use their lands.”3 See id. at 9.
    3. 1965 model act.         A few years after publication of Outdoor
    Recreation for America, the Council of State Governments proposed a
    model act relating to recreational use, the suggested title of which was
    “An act to encourage landowners to make land and water areas available
    to the public by limiting liability in connection therewith.” See Council of
    State Governments, Public Recreation on Private Lands: Limitations on
    Liability, 24 Suggested State Legislation 150, 150 (1965) [hereinafter
    Council of State Governments]. At the time, less than one-third of the
    states had enacted recreational use statutes. Id. The Council of State
    Governments recognized the lack of public outdoor recreational space
    and that a solution was to encourage private landowners to open their
    land to the public. Id. The preface to the 1965 model act stated:
    Recent years have seen a growing awareness of the
    need for additional recreational areas to serve the general
    public.    The acquisition and operation of outdoor
    3In addition to its report, the ORRRC published a series of studies. The titles
    not surprisingly demonstrate an abiding focus on outdoor recreation. The titles of the
    studies include Public Outdoor Recreation Areas—Acreage, Use, Potential; List of Public
    Outdoor Recreation Areas–1960; Wilderness and Recreation—A Report on Resources,
    Values, and Problems; Shoreline Recreation Resources of the United States; The Quality
    of Outdoor Recreation: As Evidence by User Satisfaction; and Hunting in the United
    States—Its Present and Future Role.” See Charles Zinser, Outdoor Recreation: United
    States National Parks, Forests, and Public Lands 37 (1995).
    13
    recreational facilities by governmental units is on the
    increase. However, large acreages of private land could add
    to the outdoor recreation resources available. Where the
    owners of private land suitable for recreational use make it
    available on a business basis, there may be little reason to
    treat such owners and the facilities they provide in any way
    different from that customary for operators of private
    enterprises. However, in those instances where private
    owners are willing to make their land available to members
    of the general public without charge, it is possible to argue
    that every reasonable encouragement should be given to
    them.
    In something less than one-third of the states,
    legislation has been enacted limiting the liability of private
    owners who make their premises available for one or more
    public recreational uses. This is done on the theory that it is
    not reasonable to expect such owners to undergo the risks of
    liability for injury to persons and property attendant upon
    the use of their land by strangers from whom the
    accommodating owner receives no compensation or other
    favor in return.
    Id. As indicated in the preface, the need was for additional recreational
    areas “to serve the general public.” While public land was being acquired
    by government, “large acreages of private land could add to the outdoor
    recreation resources available.”       Id.   Thus, the Council of State
    Governments proposed that the public recreational resources of the
    government should be supplemented by large acreages of private lands
    for purposes of outdoor recreation.
    Section 1 of the 1965 model act declared that its general purpose
    was “to encourage owners of land to make land and water areas available
    to the public for recreational purposes by limiting their liability toward
    persons entering thereon for such purposes.” Id.      This first section is
    consistent with the preface, emphasizing that land and water resources
    should be made available to the public.
    Section 2(c) of the 1965 model act defined “recreational purpose”
    under the act. It provided:
    14
    “Recreational purpose” includes, but is not limited to, any of
    the following, or any combination thereof: hunting, fishing,
    swimming, boating, camping, picnicking, hiking, pleasure
    driving, nature study, water skiing, winter sports, and
    viewing or enjoying historical, archaeological, scenic or
    scientific sites.
    Id. at 151 (emphasis added). Section 3 of the 1965 model act provided a
    landowner owed “no duty of care to keep the premises safe for entry or
    use by others for recreational purposes, or to give any warning of a
    dangerous condition, use, structure, or activity on such premises” to
    persons who entered the landowner’s land for recreational purposes. Id.
    The 1965 model act did not provide complete immunity to
    landowners against claims of persons entering the land for recreational
    purposes. Section 6(a) provided that the statutory immunity would not
    extend to injuries caused by “willful or malicious failure to guard or warn
    against a dangerous condition, use, structure, or activity.” Id. Similarly,
    section 6(b) provided that protection would not extend to landowners
    who charged recreational users a fee for access to their lands. Id.
    4. 1979 proposed model act. After roughly a decade of experience
    under the 1965 model act, advocates of outdoor recreation—the National
    Association of Conservation Districts, the International Association of
    Fish and Wildlife Agencies, the National Rifle Association, the National
    Wildlife    Federation,   and   the    Wildlife   Management    Institute—
    commissioned University of Wisconsin law professor William L. Church
    to conduct a study of the use of private lands for recreational purposes.
    See Church at 3; see also Stuart J. Ford, Comment, Wisconsin’s
    Recreational Use Statute: Toward Sharpening the Picture at the Edges,
    
    1991 Wis. L
    . Rev. 491, 499 & n.31 (1991) [hereinafter Ford] (referring to
    the investigation’s sponsors as “a coalition of sporting and environmental
    groups”).    Professor Church concluded that the 1965 model act was
    15
    generally too protective of recreational users and that this in turn caused
    landowners to refrain from opening land to the public for recreational
    use. See Church at 10–13. Professor Church also found the 1965 model
    act complex and unpredictable. Id. This was, in part, due to confusion
    purportedly caused by the definition of “recreational purpose.” Id. at 11.
    To cure these perceived deficiencies, Professor Church drafted what is
    generally referred to as the 1979 proposed model act. See id. at 29–33.
    Among other things, the 1979 proposed model act provided that
    “ ‘[r]ecreational use’ means any activity undertaken for exercise,
    education, relaxation, or pleasure on land owned by another.” Id. at 29
    (section 2(3)).   The 1979 proposed model act also allowed owners to
    collect certain fee-like benefits from recreational users, included
    government entities in the definition of “owners” under the statute, and
    limited potential premises liability claims of recreational users to
    malicious acts or omissions by owners. Id. at 29–30 (sections 2(2), 2(4)
    and 5(1)).
    5. Advocacy of outdoor recreation in the 1980s and 1990s. In the
    1980s and 1990s, there were a number of important meetings related to
    improving outdoor recreational access as well as a growth of literature
    relating to recreational use statutes.         In 1987, the President’s
    Commission on Americans Outdoors issued a lengthy report emphasizing
    the desirability of more outdoor recreational opportunities for Americans.
    See    President’s   Commission   on     Americans   Outdoors,   Americans
    Outdoors: The Legacy, the Challenge, with Case Studies 13–15 (Island
    Press 1987). With respect to recreational use statutes, the report noted
    that roughly forty-six states had statutes protecting private landowners
    when they provided “free public access” to their property for recreational
    use.   Id. at 202.   The report suggested expansion of recreational use
    16
    statutes to include within their scope not just recreational users but
    “volunteers” apparently associated with recreational use. Id. at 213.
    In 1990, a conference featuring participants from twenty-nine
    states and the District of Columbia promoted the need to obtain more
    public access to private land. See Proceedings from the Conference on:
    Income Opportunities for the Private Landowner Through Management of
    Natural Resources and Recreational Access i, 3 (William N. Grafton et al.
    eds., 1990).     A unifying theme of this meeting, consistent with the
    available literature, is a repeated emphasis on increasing access to
    outdoor recreation for members of the public.          See id. at 3.    The
    conference sought to instruct private landowners as to the potential
    profitability of opening their lands for a fee and potential liability
    associated with doing so.     See id. at 60, 341–80.     In particular, one
    commentator noted that “[r]ecreational use statutes are intended to
    encourage owners of private land to allow the public to enter without
    charge for recreational purposes such as hiking, exploring caves,
    swimming and other such activities.” Id. at 370.
    In 1999, an assessment of outdoor recreation was published
    pursuant to the Forest and Rangeland Renewable Resources Planning
    Act of 1974. See H. Ken Cordell et al., Outdoor Recreation in America: A
    National Assessment of Demand and Supply Trends vii (Susan M.
    McKinney ed., 1999). In a chapter entitled “Private Lands and Outdoor
    Recreation in the United States,” the report noted that “increasing
    demand for outdoor recreation in America brings into play the question of
    liability.” Id. at 184 (emphasis added).
    B. Definitions of “Recreational Purpose” in Recreational Use
    Statutes.      Currently, all states have some kind of recreational use
    statute.    While there is considerable variety in the recreational use
    17
    statutes, the statutes fall into a number of general categories with
    respect to the manner in which they define “recreational purpose.” These
    include statutes that define “recreational purpose” using the “includes,
    but is not limited to” language of the 1965 model act followed by a list of
    activities. Other statutes are patterned after the 1979 proposed model
    act.    Some statutes are hybrids and contain expansive catchall
    provisions in addition to a list of activities. Finally, others take a more
    restrictive approach.
    1. Recreational use statutes with a definition of recreational use
    patterned after the 1965 model act. Many states have recreational use
    statutes that define “recreational purpose” using a list that “includes but
    is not limited to” a number of specific outdoor activities.       The list of
    activities specifically identified in the statutes varies from state to state,
    but usually includes the activities identified in the 1965 model act with
    the addition of other activities, such as spelunking, hot air ballooning,
    gleaning, mushing, and hang gliding.         See Ala. Code § 35–15–21(3)
    (LexisNexis 1991); Ark. Code Ann. § 18–11–302(5) (Supp. 2011); Conn.

    Wyo. Stat. Ann. § 34–19–101(a)(iii) (2011); see also Cal. Civil Code § 846
    (West 2007).
    A number of courts have pointed to “includes, but is not limited to”
    language to support expansive interpretations of recreational use
    statutes. See, e.g., Anderson v. Atlanta Comm. for the Olympic Games,
    Inc., 
    537 S.E.2d 345
    , 348 (Ga. 2000) (interpreting the “includes, but is
    not limited to” language of the Georgia statute to mean that the statute
    encompasses any recreational activity); Jacobsen v. City of Rathdrum,
    
    766 P.2d 736
    , 743 (Idaho 1988) (finding that a child who was “playing”
    had a recreational purpose even though such activity was not expressly
    listed); Richard v. La. Newpack Shrimp Co., 
    82 So. 3d 541
    , 546 (La. Ct.
    App. 2011) (holding the omnibus clause incorporated loading a boat and
    preparing for departure into the statute even though they were not
    expressly listed). California’s statute is slightly different in that it states,
    “A ‘recreational purpose,’ as used in this section, includes such activities
    as . . . .” Cal. Civil Code § 846 (emphasis added). It has, however, been
    interpreted expansively because it uses a term of enlargement followed
    by a list of activities, see Ornelas v. Randolph, 
    847 P.2d 560
    , 563 (Cal.
    1993) (holding that playing on farm equipment is a recreational purpose
    within the meaning of the statute even though not specifically listed), and
    is therefore similar to those statutes using the “includes, but is not
    limited to” language of the 1965 model act.
    2. Statutes that incorporate the expansive language of the 1979
    proposed model act. Some statutes use expansive general language to
    define “recreational purpose.”      These statutes appear to be modeled
    19
    directly after the 1979 proposed model act. See N.C. Gen. Stat. § 38A–
    2(5) (2012) (“ ‘Recreational purpose’ means any activity undertaken for
    recreation, exercise, education, relaxation, refreshment, diversion, or
    pleasure.”); N.D. Cent. Code § 53–08–02 (2012) (“ ‘Recreational purposes’
    includes any activity engaged in for the purpose of exercise, relaxation,
    pleasure, or education.”). Similarly, prior to an amendment in 2005, the
    Illinois recreational use statute, which also applies to conservation
    purposes, defined “ ‘recreational or conservation purpose’ ” as “ ‘any
    activity undertaken for conservation, resource management, exercise,
    education, relaxation, or pleasure on land owned by another.’ ”4 See Hall
    v. Henn, 
    802 N.E.2d 797
    , 799 (Ill. 2003) (quoting 745 Ill. Comp. Stat.
    Ann. 65/2(c) (West 2002)); see also 2005 Ill. Laws ch. 70, para. 32
    (amending this definition to include only hunting and recreational
    shooting).
    As expected, courts have interpreted these statutes broadly. See,
    e.g., Vaughn v. Barton, 
    933 N.E.2d 355
    , 363 (Ill. App. Ct. 2010) (holding
    the pre-2005-amendment Illinois statute applied to playing baseball and
    watching baseball); Olson v. Bismarck Parks & Recreation Dist., 
    642 N.W.2d 864
    , 871 (N.D. 2002) (holding that winter sledding is a
    recreational purpose under the North Dakota statute).                     As the Illinois
    Supreme Court put it, “ ‘Exercise, education, relaxation, or pleasure’
    encompasses just about every purpose, absent commerce, for which a
    4Prior   to 1987, the Illinois definition of “recreational purpose” was markedly
    different. It stated,
    “ ‘Recreational purpose’ includes, and is limited to, any of the following, or
    any combination thereof: hunting, fishing, swimming, boating,
    snowmobiling, motorcycling, camping, picnicking, hiking, cave exploring,
    nature study, water skiing, water sports, bicycling, horseback riding, and
    viewing or enjoying historical, archaeological, scenic or scientific sites.”
    Lane v. Titchenel, 
    562 N.E.2d 1194
    , 1197 (Ill. App. Ct. 1990) (quoting the 1985 version
    of the definition).
    20
    person is invited onto another’s property.”              Hall, 802 N.E.2d at 800.
    Maryland, interestingly, has chosen to define “recreational purpose” as
    encompassing “any recreational pursuit,” a definition that may be
    broader than that of the 1979 proposed model act. See Md. Code Ann.,
    Nat. Res. § 5–1101(f) (LexisNexis 2012).5
    3. Recreational use statutes with a definition of “recreational
    purpose” containing expansive catchall provisions.               Several states have
    departed from the 1965 model act by providing catchall language in the
    definition of recreational purpose. These statutes are essentially hybrids
    of the 1965 model act and the 1979 proposed model act in that they
    define “recreational purpose” using a list of activities coupled with a
    catchall provision. Some of these states simply provide that the statute
    includes “other recreational activities,” an approach that may be
    criticized as circular.      See Colo. Rev. Stat. § 33–41–102(5) (2012) (“or
    other recreational activity”); Ind. Code Ann. § 14–22–10–2(d) (LexisNexis
    2003) (“for the purpose of swimming, camping, hiking, sightseeing, or
    any other purpose”); Mich. Comp. Laws Ann. § 324.73301 (West 2009)
    (“or any other outdoor recreational use or trail use”); Mont. Code Ann.
    § 70–16–301 (2011) (“or other pleasure expeditions”); N.J. Stat. Ann.
    § 2A:42A–2 (West 2010) (“and any other outdoor sport”); N.M. Stat. Ann.
    § 17–4–7 (2012) (“or any other recreational use”); Va. Code Ann. § 29.1–
    509(B) (2011) (“for any other recreational use”); see also Ariz. Rev. Stat.
    Ann. § 33-1551(c)(5) (Supp. 2012) (defining “recreational user” as one
    who may “engage in other outdoor recreational pursuits” in addition to
    other enumerated activities); Ohio Rev. Code Ann. § 1533.18(B)
    5This is in stark contrast to a former version of Maryland’s statute, which stated,
    “ ‘Recreational purpose’ includes the following or any combination thereof . . .” and did
    not include a catchall provision. See 1973 Md. Laws, 1st Extra. Sess., 827.
    21
    (LexisNexis Supp. 2012) (defining “recreational user” as one who engaged
    in certain enumerated activities “or to engage in other recreational
    pursuits”). In addition, the Colorado statute uses the “includes, but is
    not limited to” language of the 1965 model act. See Colo. Rev. Stat. 33–
    41–102(5); see also Mont. Code Ann. § 70–16–301 (indicating that the
    definition “includes” certain activities).
    In particular, Indiana courts have focused on the “or any other
    purpose” language to hold that the Indiana statute applies when a land
    user engages in certain activities that are not enumerated.               See
    Cunningham v. Bakker Produce, Inc., 
    712 N.E.2d 1002
    , 1006 (Ind. Ct.
    App. 1999) (baseball); McCormick v. State, 
    673 N.E.2d 829
    , 833–34 (Ind.
    Ct. App. 1996) (boating); Kelly v. Ladywood Apartments, 
    622 N.E.2d 1044
    , 1048 (Ind. Ct. App. 1993) (sledding). But, the Indiana Supreme
    Court also held that a high school student who decorated an abandoned
    grain elevator and participated in a haunted house performance was not
    engaged in a recreational activity           because   those activities   were
    inconsistent with the outdoor activities specifically mentioned in the
    statute, which included hunting, fishing, swimming, trapping, camping,
    hiking, and sightseeing. Drake ex rel. Drake v. Mitchell Cmty. Sch., 
    649 N.E.2d 1027
    , 1030 (Ind. 1995).
    4. Recreational use statutes that list recreational uses, but do not
    include expansive language. Unlike the statutes identified above, a very
    small number of states comprise a fourth category with a more restrictive
    approach to defining “recreational purpose.” These states’ recreational
    use statutes list outdoor activities that qualify as recreational uses, but
    do not contain the “includes, but is not limited to” language of the 1965
    model act or the more expansive definitional language of the 1979
    proposed model act. For example, New York’s statute provides that “an
    22
    owner, lessee or occupant of premises . . . owes no duty to keep the
    premises safe for entry or use by others for [specified recreational
    activities].” N.Y. Gen. Obligations Law § 9–103 (McKinney’s 2010). The
    New York Court of Appeals has interpreted this to mean that the land
    user must be engaged in one of the enumerated activities.         Bragg v.
    Genesee Cnty. Agric. Soc’y, 
    644 N.E.2d 1013
    , 1016 (N.Y. 1994). As will
    be explained below, Iowa’s statute takes a restrictive approach similar to
    New York’s.
    Illinois has taken an even more restrictive approach. Although its
    recreational use statute originally defined “recreational purpose” using
    the “includes, but is not limited to” language of the 1965 model act and
    later included the sweeping definitional language of the 1979 proposed
    model act, the Illinois legislature severely restricted the statute in 2005
    by amending it to apply only to “hunting or recreational shooting.” See
    2005 Ill. Laws ch. 70, para. 32.
    IV. Iowa’s Recreational Use Act.
    The Iowa recreational use statute was enacted in 1967, two years
    after publication of the 1965 model act. See 1967 Iowa Acts ch. 149.
    Although the legislature based the statute on the 1965 model act, the
    legislature made important alterations prior to its enactment that are
    relevant to our decision today.
    The recreational use act was proposed as H.F. 151 and entitled
    according to the suggestion of the 1965 model act as “[a]n Act to
    encourage landowners to make land and water available to the public by
    limiting liability in connection therewith.” H.F. 151, 62d G.A., Reg. Sess.
    (Iowa 1967); see also Council of State Governments, 24 Suggested State
    Legislation at 150. The text and explanation of H.F. 151 as originally
    proposed were substantially the same as the text and preface of the 1965
    23
    model act. Compare H.F. 151, with Council of State Governments, 24
    Suggested State Legislation at 150–52. See also City of Cedar Rapids v.
    James Props., Inc., 
    701 N.W.2d 673
    , 677 (Iowa 2005) (“We give weight to
    explanations attached to bills as indications of legislative intent.”). H.F.
    151 spelled out a need to encourage private landowners to make their
    lands available by defining any potential liability. H.F. 151, explanation.
    As the legislature explained, “Recent years in Iowa have shown a growing
    need for additional recreational areas for use by our citizenry.”       Id.;
    accord Scott v. Wright, 
    486 N.W.2d 40
    , 42 (Iowa 1992). It further pointed
    to the roughly one-third of other states that had already passed
    recreational use laws because it was unreasonable to expect private
    landowners to risk liability to persons from whom they would receive no
    compensation in return.     H.F. 151, explanation.    It stands to reason,
    therefore, that the legislature modeled the recreational use statute after
    the 1965 model act. Peterson v. Schwertley, 
    460 N.W.2d 469
    , 470 (Iowa
    1990).
    Although the original proposed definition of “recreational purpose”
    in H.F. 151 was identical to the definition in the 1965 model act,
    compare H.F. 151 § 2(3), with Council of State Governments, 24
    Suggested State Legislation at 151 (section 2(c)), the legislature adopted
    two important amendments prior to enactment. One amendment struck
    the words “includes, but is not limited to, any of” and inserted in lieu
    thereof the word “means.”     Another amendment added “while going to
    and from or actually engaged therein” to the end of the 1965 model act’s
    definition. Thus, the enacted definition of “recreational purposes” read
    as follows:
    “Recreational purpose” means the following or any
    combination thereof: hunting, fishing, swimming, boating,
    camping, picnicking, hiking, pleasure driving, nature study,
    24
    water skiing, winter sports, and viewing or enjoying
    historical, archeological, scenic, or scientific sites while going
    to and from or actually engaged therein.
    1967 Iowa Acts ch. 149, § 2 (emphasis added). From these amendments
    we can conclude the legislature considered and deliberately rejected the
    expansive “includes, but is not limited to” language of the 1965 model
    act defining “recreational purpose,” choosing instead a definition
    consisting of a closed universe of terms. See 2B Norman J. Singer & J.D.
    Shambie Singer, Statutes & Statutory Construction § 52:5, at 370 (rev.
    7th ed. 2012) (noting that ordinarily “when a legislature models a statute
    after a uniform act, but does not adopt particular language, courts
    conclude the omission was ‘deliberate’ or ‘intentional,’ and that the
    legislature rejected a particular policy of the uniform act”).
    Over the years, the legislature has amended this definition various
    times. In 1971, the legislature added “horseback riding,” “motorcycling,”
    “snowmobiling,” and “other summer . . . sports.” 1971 Iowa Acts chs.
    129–30.      In 1988, the legislature amended the statute to include
    “trapping.” 1988 Iowa Acts ch. 1216, § 46. Finally, in 2012, although
    subsequent to the incident giving rise to the issue in this case, the
    legislature amended the statute to include “all-terrain vehicle riding.”
    2012 Iowa Acts ch. 1100, § 58.6
    6The legislature also made Iowa’s recreational use statute applicable to activities
    involving “urban deer control.” See 2006 Iowa Acts ch. 1121. The legislature added
    these provisions much in the same way that Arizona and Maryland made their statutes
    applicable to educational activities and South Dakota made its statute applicable to
    agritourism activities in addition to recreational activities.       Compare Iowa Code
    § 461C.1 (2009), with Ariz. Rev. Stat. Ann. § 33–1551(A) (Supp. 2012), Md. Code Ann.,
    Nat. Res. § 5–1102(a) (LexisNexis 2012), and S.D. Codified Laws 20–9–13 (Supp. 2012).
    Each of these statutes applies to limit landowner liability to persons engaged in these
    activities in addition to limiting landowner liability to persons engaged in recreational
    activities and provides separate definitions for each. See Ariz. Rev. Stat. Ann. § 33–
    1551(C)(1), (5); Iowa Code § 461C.2(5), (6); Md. Code Ann., Nat. Res. § 5–1101(c), (f);
    S.D. Codified Laws 20–9–12(3), (4).
    25
    Notably, the legislature never added the “includes, but is not
    limited to” language of the 1965 model act as roughly half of the other
    states have done. Similarly, it never added a catchall provision, such as
    those contained in the definitions of Arizona, Colorado, Indiana,
    Michigan, Montana, New Jersey, New Mexico, Ohio, and Virginia.
    Further, the Iowa legislature has not adopted the expansive definition of
    “recreational purpose” from the 1979 proposed model act as in North
    Carolina and North Dakota.
    Instead, Iowa’s statute provides that “ ‘[r]ecreational purpose’
    means the following or any combination thereof,” just as it has since its
    enactment. Iowa Code § 461C.2(5) (2009) (emphasis added). By doing
    so, the Iowa legislature created a closed universe of outdoor activities
    that trigger the protections of the statute.      The legislature has thus
    determined that if some other activity beyond those specifically listed is
    to be considered a recreational purpose, legislative action is required.
    This is demonstrated by the legislature’s decision to add specific terms to
    the definition over the years. Given the closed nature of the definition of
    “recreational   purposes”    under    the     statute,   horseback   riding,
    snowmobiling, other summer sports, trapping, and all-terrain vehicle
    riding would not have been within the scope of Iowa’s recreational use
    statute absent legislative action.
    V. State Court Interpretation of Recreational Use Statutes.
    A review of cases demonstrates that most state courts have
    construed recreational use statutes to achieve the legislative purpose of
    opening lands for outdoor recreation.       See Jim Butler, Outdoor Sports
    and Torts: An Analysis of Utah’s Recreational Use Act, 
    1988 Utah L
    . Rev.
    47, 65–66 (1988). The question in these cases is not so much whether
    the statute should be limited to achieve its purposes, but rather what
    26
    kind of limitation should be adopted. Regardless of the type of limitation,
    the purpose of limitation is clear: to avoid the absurd result identified by
    the plaintiff in this case, namely, that the recreational use statute applies
    to an urban dweller’s barbecue party or a basketball game in the
    driveway of a suburban home.
    A. General Limitations on the Reach of Recreational Use
    Statutes.
    1. Generally open to the public. One approach to limit the scope of
    a recreational use statute is to require landowners to make their land
    open to the public generally in order to be entitled to immunity. In the
    often cited case of Gibson v. Keith, the Delaware Supreme Court held that
    Delaware’s statute applied only to landowners who invite or permit
    without charge the public at large to use property for recreational
    purposes.

    911 P.2d 1290
    , 1293 (Utah 1996);
    Cregan v. Fourth Mem’l Church, 
    285 P.3d 860
    , 863–64 (Wash. 2012);
    LePoidevin v. Wilson, 
    330 N.W.2d 555
    , 562–63 (Wis. 1983).
    These cases suggest the land in question must be generally
    available to the public—akin to a privately owned but public park—in
    order for the immunity to apply.7 See Copeland at 26 (“Recreational use
    statutes protect landowners from liability claims only if land in question
    7Severalstates have expressly adopted this requirement. See, e.g., Conn. Gen.
    Stat. Ann. § 52–557(g)(a) (2005); Wash. Rev. Code Ann. § 4.24.210(1) (West Supp.
    2013).
    27
    is made accessible to the public.”).     Other cases, however, reject this
    requirement.    See Collins v. Martella, 
    17 F.3d 1
    , 4 (1st Cir. 1994)
    (interpreting the New Hampshire statute); Mansion v. United States, 
    945 F.2d 1115
    , 1117–18 (9th Cir. 1991) (interpreting the California statute);
    Barrett v. Pa. Gas & Water Co., 
    631 F. Supp. 731
    , 733–34 (M.D. Pa.
    1985); Johnson v. Stryker Corp., 
    388 N.E.2d 932
    , 934 (Ill. App. Ct. 1979).
    2. “True outdoors” test. In a number of cases, state courts have
    limited the scope of recreational purpose to activities associated with the
    true outdoors. For example, in Keelen v. State, the Louisiana Supreme
    Court stated that based on the specified activities in the statute the
    “legislature envisioned immunity for landowners who offer their property
    for recreation that can be pursued in the ‘true outdoors.’ ” 
    463 So. 2d 1287
    , 1290 (La. 1985).      Accordingly, even though the case involved
    swimming in a pool and swimming was an enumerated activity in the
    statute, the court held the statute only covered “swimming in lakes,
    rivers, ponds or other similar bodies of water.”    Keelen, 463 So. 2d at
    1290–91.   Similarly, in Wymer the Michigan Supreme Court held that
    diving into a shallow pond in an urban setting was not among the
    “outdoor” activities included under the statute.        412 N.W.2d at 219.
    According to the Wymer court, “The commonality among all these
    enumerated uses is that they generally require large tracts of open,
    vacant land in a relatively natural state.”       Id.    In Quesenberry v.
    Milwaukee County, the Wisconsin Supreme Court refused to grant
    recreational use immunity to the owner of a golf course, noting that the
    activities qualifying as recreational purpose were normally done on land
    in its “natural undeveloped state as contrasted to the more structured,
    landscaped and improved nature of a golf course.” 
    317 N.W.2d 468
    , 472
    (Wis. 1982). In Dykes v. Scotts Bluff County Agricultural Society, Inc., the
    28
    Nebraska Supreme Court held that viewing livestock events at a county
    fair was not a recreational purpose under Nebraska’s recreational use
    statute because “the activities listed in [the statute] are more physical
    than not, generally require the outdoors, and are not ‘spectator sports.’ ”
    
    617 N.W.2d 817
    , 823 (Neb. 2000); see also Boileau v. De Cecco, 
    310 A.2d 497
    , 499–500 (N.J. Super. Ct. App. Div. 1973), aff’d, 
    323 A.2d 449
     (N.J.
    1974); Matthews v. Elk Pioneer Days, 
    824 P.2d 541
    , 542–44 (Wash. Ct.
    App. 1992).8
    Collectively, these cases stand for the proposition that recreational
    use statutes are not sweeping immunity statutes that generally overturn
    ordinary tort liability for all landowners, including urban residents, but
    are instead more focused statutes that should be interpreted consistently
    with the underlying legislative purpose of enhancing outdoor recreational
    opportunities.9       Recreational use statutes are designed to cover
    situations such as when a recreational user trips over a log, twists an
    ankle in a ground hog burrow, or falls down a ravine hidden by brush
    while they are on private property to hunt, fish, hike, or the like, not
    incidents involving a backyard barbecue or a friendly game of hoops in
    suburbia.
    3. Causal link between injury and recreational use. As noted by
    one authority, “courts have routinely ruled that persons entering land to
    engage in activities outside the scope of the activities outlined in the
    8There  is contrary authority. See Iannotti v. Consol. Rail Corp., 
    542 N.E.2d 621
    ,
    623 (N.Y. 1979) (noting the New York recreational use statute “is not limited to claims
    arising in wilderness, remote or undeveloped areas”).
    9Some  state recreational use statutes specifically refer to “outdoor recreational
    purposes,” “outdoor recreational use,” or “any other outdoor sport.” See, e.g., Mich.
    Comp. Laws § 324.73301 (West 2009); Miss. Code Ann. § 89–2–3 (West 1999); N.J. Stat.
    Ann. 2A:42A–2 (2010); Oklahoma, § 10.1 (2012); S.D. Codified Laws sec. 20–9–13
    (Supp. 2012).
    29
    statute are not classified as recreational users.”   Carroll, 17 J. Legal
    Aspects of Sport at 173. For instance, in Rintelman v. Boys & Girls Clubs
    of Greater Milwaukee, Inc., a chaperone at an educational retreat who
    slipped and fell on a path was found to be walking on the path in
    connection with her duties as a chaperone and not for a recreational
    purpose. 
    707 N.W.2d 897
    , 905–06 (Wis. Ct. App. 2005). Similarly, in
    Herman v. City of Tuscon, the court found that an employee of a food
    vendor who was injured while walking from the parking lot toward a
    band shell to work as a concessionaire at a music festival was not a
    recreational user within the meaning of the Arizona recreational use act.
    
    4 P.3d 973
    , 979 (Ariz. Ct. App. 1999). In Hontert v. Ohio Department of
    Natural Resources, the court held a plaintiff who was injured inside a
    building, an historic home, located on recreational land was not a
    recreational user because her activities in the building consisted of
    taking a tour, viewing a movie about the premises, and shopping in the
    gift shop.   
    572 N.E.2d 869
    , 872 (Ohio Ct. Cl. 1990).     In Harrison v.
    Middlesex Water Co., the Supreme Court of New Jersey held that an
    individual seeking to rescue two children who had fallen into a frozen
    pond was not engaged in a recreational use. 
    403 A.2d 910
    , 915 (N.J.
    1979).
    Similarly, in Crichfield v. Grand Wailea Co., a land user who
    asserted she was on a hotel’s property to eat lunch was injured when she
    left a footpath to admire the hotel’s fishpond and statuary. 
    6 P.3d 349
    ,
    351, 353 (Haw. 2000). The Hawai’i Supreme Court held that while there
    was a genuine issue of material fact as to whether the land user was on
    the hotel’s premises for commercial or recreational purposes, the Hawai’i
    recreational use statute would not immunize the hotel if she was on the
    premises for a commercial purpose.       Crichfield, 6 P.3d at 359–61.
    30
    Finally, in Gerkin v. Santa Clara Valley Water District, the court
    determined that where a party was walking her bicycle over a bridge in
    order to use a telephone at a nearby market and procure a candy bar,
    there was a material issue of triable fact as to whether she was “hiking”
    within the scope of the statute. 
    157 Cal. Rptr. 612
    , 615–16 (Ct. App.
    1979). The court further noted that the “purpose of the journey” should
    be considered in making this determination. Gerkin, 157 Cal. Rptr. at
    616.
    At the very least, these cases stand for the proposition that, even if
    the injured individual is on land that might be available for recreational
    use, that individual may not have been using the land in a recreational
    fashion and is therefore removed from the purview of the statute. But
    see Seminara v. Highland Lake Bible Conference, 
    492 N.Y.S.2d 146
    , 148
    (App. Div. 1985) (holding that bicycling across property to retrieve
    forgotten jacket was recreational). Therefore, while horseback riding may
    have been within the scope of the statute in this case, frolicking in the
    hayloft may not be. Further, if a party seeking to preserve the safety of
    children engaged in outdoor recreation through rescue is not within the
    scope of a recreational use statute as in Harrison, it stands to reason
    that a chaperone who stands at the ready might not be within the statute
    either.
    Other cases hold that while a trip may have had recreational
    components, a nonrecreational use of land was not covered by the
    statute.   For example, in Smith v. Scrap Disposal Corp., an individual
    entered the property to fish, which was an activity clearly covered by the
    California recreational use statute.    
    158 Cal. Rptr. 134
    , 136 (Ct. App.
    1979).     When leaving, however, the individual was injured when he
    hopped onto a bulldozer in an attempt to stop his friend from using it.
    31
    Smith, 158 Cal. Rptr. at 136.       The court held that getting onto the
    bulldozer was not a recreational use within the scope of the statute, even
    though the injury happened while returning from a covered activity. Id.
    at 137. Similarly, in James v. Metro North Commuter Railroad, the court
    held that a man fishing on a railroad bank was not engaged in
    recreational use when he crossed the tracks in an effort to rescue his
    dog. 
    560 N.Y.S.2d 459
    , 460–61 (1990).
    There are, however, contrary cases. See, e.g., Thompson v. Kyo–Ya
    Co., 
    146 P.3d 1049
    , 1057–58 (Haw. 2006) (holding a scuba diving
    instructor was on property for recreational purpose when she tripped on
    a path while leading a group of students from the ocean to the parking
    lot); Hafford v. Great N. Nekoosa Corp., 
    687 A.2d 967
    , 968–69 (Me. 1996)
    (holding an outfitter supplying canoeing and camping enthusiasts was
    engaged in activity with a recreational purpose when transporting his
    staff to pick up his clients’ vehicles).   Nonetheless, the individuals in
    these cases were engaged in a business purpose, not a recreational
    purpose, and thus the immunity should not apply to them. Further, in
    both cases, the courts seemed preoccupied with the fact that the injured
    persons were receiving a direct financial benefit from their activities on
    the land. Such a consideration is not present here.
    4. Invited guest exception.     Some courts have held that the
    immunity does not apply to invited guests.        For instance, a Georgia
    appellate court held that the immunity statute did not apply where a
    neighbor invited friends to his backyard pool without charge.         See
    Herring, 165 S.E.2d at 199. Further, several statutes expressly contain
    an invited guest exception.   See, e.g., Cal. Civ. Code § 846; Ind. Code
    Ann. § 14–22–10–2(f)(1)(B); Wis. Stat. Ann. 895.52(6)(d) (West Supp.
    2012).
    32
    5. Ancillary structures associated with land.   A number of cases
    have considered whether injuries occurring in buildings and structures
    fall within the immunity provisions of the acts. One distinction in these
    cases turns on the nature of the land upon which the building sits. For
    example, in Rivera v. Philadelphia Theological Seminary of St. Charles
    Borromeo, Inc., the Supreme Court of Pennsylvania concluded that the
    words “buildings, structures and machinery or equipment when attached
    to the realty” in the Pennsylvania recreational use act was limited “to
    ancillary structures attached to open space lands made available for
    recreation and not to an enclosed recreational facilities in urban
    regions,” such as an indoor swimming pool. 
    507 A.2d 1
    , 15 (Pa. 1986).
    Another distinction turns on the type of activity occurring within
    the structure. See Drake ex rel. Drake, 649 N.E.2d at 1030 (holding a
    student who decorated an abandoned grain elevator and participated in a
    haunted house performance was not present for a recreational purpose);
    Hontert, 572 N.E.2d at 872 (holding a tour of an historic home, which
    included an educational movie and a stop at the gift shop, was not a
    recreational use, even though the home was located on a farm). But see
    Curtiss v. County of Chemung, 
    433 N.Y.S.2d 514
    , 515 (App. Div. 1980)
    (determining the recreational use statute barred recovery where the
    plaintiffs’ presence in a storage shed was incidental to their entry to and
    use of the premises for hunting and hiking).
    The bottom line is that while under some circumstances activities
    within a building might give rise to immunity under the statute, there
    must nonetheless be activity within the structure that amounts to a
    recreational purpose.
    B. Interpretation of Elastic Recreational Use Provisions. Even
    under statutes with catchall provisions expanding the scope of the
    33
    definition of “recreational purpose,” courts have still required that the
    land user’s activities be outdoor recreational purposes in order to trigger
    immunity.      For example, in Villanova v. American Federation of
    Musicians, Local 16, the court held that the phrase “other outdoor sport,
    game and recreational activity” did not manifest a legislative intent to
    bring within the statute’s ambit recreational activities that were “forms of
    play, amusement, diversion or relaxation.”      
    301 A.2d 467
    , 468 (N.J.
    Super. Ct. App. Div. 1973); see also Drake ex rel. Drake, 649 N.E.2d at
    1030 (decorating a grain elevator and participating in a haunted house
    performance was not “any other purpose”); Keelen, 463 So. 2d at 1291
    (holding a swimming pool in a state park is not the type of recreation in
    the true outdoors); Eschete v. Mecom, 
    509 So. 2d 840
    , 843 (La. Ct. App.
    1987) (holding the Louisiana recreational use statute did not bar
    recovery by a plaintiff who suffered injuries when his boat struck a
    submerged oil well cribbing in a canal because the injuries were not
    caused by instrumentalities one would normally encounter in the true
    outdoors and were instead a man-made trap for the unwary); Boileau,
    310 A.2d at 499–500 (holding that swimming in a swimming pool was
    not a “sport or recreational activity” because the New Jersey statute was
    designed to cover activity conducted in the true outdoors, not in
    someone’s backyard); Hontert, 572 N.E.2d at 872 (viewing a movie and
    shopping in a gift shop not “other recreational pursuits”).
    A federal district court took a somewhat different approach to an
    elastic provision in Fisher v. United States, 
    534 F. Supp. 514
     (D. Mont.
    1982).   In this case, a child died while playing on a snowplow during
    lunchtime on a school field trip.     Fisher, 534 F. Supp. at 515.      The
    question was whether the Montana statute, which provided that
    recreational   purposes   included   “picnicking”   and   “other   pleasure
    34
    expeditions,” barred the suit. Id. The court concluded Montana’s list of
    recreational purposes was not exclusive and that the statute should be
    interpreted to include school field trips within its scope. Id. at 515–16.
    Yet, Fisher has not been widely cited, is inconsistent with a California
    appellate court’s decision in Scrap Disposal, and was construing a
    statute containing an expansive catchall provision.      The Iowa statute
    does not contain such language.
    C. Interface Between Tort Law and Recreational Use Statutes.
    Courts have also limited application of recreational use statutes to tort
    claims related to premises liability. The common thread in these cases is
    that premises liability claims are separate from other negligence claims.
    For example, in Klein v. United States a cyclist was struck by an
    automobile driven by the landowner’s employee. 
    235 P.3d 42
    , 44 (Cal.
    2010).    The California Supreme Court held that the California
    recreational use statute related to premises liability, not other tortious
    conduct, and did not extend to acts of vehicular negligence by a
    landowner or a landowner’s employee.      Klein, 235 P.3d at 44, 49–50.
    Similarly, in Dickinson v. Clark, a case in which a minor was injured by a
    wood splitter, the Supreme Judicial Court of Maine held the statute
    applied only to premises liability claims and not to claims of negligent
    supervision or instruction. 
    767 A.2d 303
    , 305–06 (Me. 2001). Moreover,
    the   Wisconsin   Supreme    Court   considered   the   interface   between
    traditional tort law and a recreational use statute in LePoidevin. There,
    the plaintiff was injured when she dove from the defendant’s pier into
    shallow water. LePoidevin, 330 N.W.2d at 557. The defendant’s son and
    son-in-law were allegedly ridiculing, taunting, and challenging the
    plaintiff to enter the water and grabbed her towel away from her. Id. The
    35
    court held the active negligence on the part of the defendants took the
    plaintiff’s claim outside the scope of the statute. Id. at 560.
    VI. Iowa Case Law.
    In Peterson, the plaintiff and his friends were swimming in a lake
    near a large tree. 460 N.W.2d at 470. Land users frequently attached
    ropes to the tree in order to swing out over the water. Id. at 469. The
    tree also had pieces of wood nailed to its trunk, which facilitated
    climbing into the tree. Id. at 469–70. The landowner had attempted to
    discourage swimming on his property by occasionally removing ropes
    and the pieces of wood from the tree.         Id.   He also posted “private
    property—no trespassing” signs.         Id. at 470.      The plaintiff, who
    apparently ignored the posted signs, was paralyzed when he reached for
    a rope suspended from the tree without the landowner’s permission, lost
    his balance, decided to dive into the water, and hit his head. Id. The
    question was whether the landowner had an obligation to keep the
    premises safe for trespassers. Id. at 471. We held that the recreational
    statute extended to trespassers and immunized the landowner.          Id. at
    471–72.
    In Scott, we considered the relationship between immunity in
    Iowa’s recreational use statute and negligence claims. There, a birthday
    party guest was injured when she fell from a wagon and became trapped
    beneath it during a hay ride on the defendant’s property.         Scott, 486
    N.W.2d at 41. Because the tractor pulling the wagon was driven by the
    defendants’ daughter, the guest sought to recover on a theory of
    vicarious liability for the driver’s negligent operation of the tractor. Id.
    After a verdict for the plaintiff, the defendant appealed, claiming that the
    recreational use statute prevented recovery. Id. at 41–42.
    36
    We declined to disturb the jury verdict. We noted that nothing in
    the legislative history of the recreational use statute “suggests a
    legislative intent to immunize all negligent acts of landowners, their
    agents, or employees.” Id. at 42. We emphasized that the statute was
    enacted to serve “ ‘a growing need for additional recreation areas for use
    by our citizenry.’ ” Id. (quoting H.F. 151, 62 G.A., Reg. Sess. explanation
    (Iowa 1967)).   We further stated, “The public’s incentive to enter and
    enjoy private agricultural land would be greatly diminished if users were
    subject, without recourse, to human error as well as natural hazards.”
    Id.
    In reaching the conclusion that the statute was so limited, we
    emphasized that the language of the recreational use statute is “couched
    in terms of premises liability.”   Id.   (emphasis added).     In short, the
    inquiry after Scott is whether the claim is based upon human error or
    natural hazards. If the claim is based upon natural hazards, it is barred
    by the recreational use statute, which extinguishes premises liability
    claims. If, however, the claim is based upon human error, the immunity
    provided by the recreational use statute has no application.
    VII. Analysis of Applicability of Recreational Use Statute.
    A. Framework for Interpretation of Iowa’s Recreational Use
    Statute. In interpreting a statute, “[w]e consider the objects sought to
    be accomplished and the evils and mischiefs sought to be remedied.”
    Klinge v. Bentien, 
    725 N.W.2d 13
    , 18 (Iowa 2006) (citation and internal
    quotation marks omitted). We seek to advance, rather than defeat, the
    purposes of the statute.    State v. Tesch, 
    704 N.W.2d 440
    , 451 (Iowa
    2005).
    When a statute is ambiguous, we look to extrinsic materials to aid
    in interpretation. State v. Hearn, 
    797 N.W.2d 577
    , 586 (Iowa 2011). A
    37
    statute is ambiguous if reasonable minds could differ as to its meaning.
    Holiday Inns Franchising, Inc. v. Branstad, 
    537 N.W.2d 724
    , 728 (Iowa
    1995). Ambiguity may arise from the meaning of particular words in the
    statute or from the general scope and meaning of the statute when
    considered as a whole. Carolan v. Hill, 
    553 N.W.2d 882
    , 887 (Iowa 1996).
    If a statute is ambiguous, we may consider, among other matters, “[t]he
    object sought to be obtained,” “[t]he circumstances under which the
    statute was enacted,” “[t]he legislative history,” “[t]he common law or
    former statutory provisions,” “[t]he consequences of a particular
    construction,” “[t]he administrative construction of the statute,” and
    “[t]he preamble or statement of policy.” Iowa Code § 4.6.
    Courts and commentators have generally noted that recreational
    use statutes have many ambiguities.      John C. Becker, Landowner or
    Occupier Liability for Personal Injuries and Recreational Use Statutes: How
    Effective is the Protection?, 
    24 Ind. L
    . Rev. 1587, 1613 (1991) (citing a
    need to clarify ambiguities affecting the coverages and applications of
    recreational use statutes in specific situations); Ford, 
    1991 Wis. L
    . Rev.
    at 527 (noting that the concept of recreation is amorphous and difficult
    to define unambiguously); Glen Rothstein, Note & Comment, Recreational
    Use Statutes and Private Landowner Liability: A Critical Examination of
    Ornelas v. Randolph, 15 Whittier L. Rev. 1123, 1125–26 (suggesting that
    inadequate and ambiguous definitions of lands, users, and activities
    covered by recreational use statutes cause disagreements over their
    application). The lengthy COA and ALR annotations are testament to the
    many difficulties associated with interpretation of recreational use
    statutes. See generally James Lockhart, Annotation, Cause of Action for
    Personal Injury or Death in Which Recreational Use Statute is Raised as a
    Defense, 18 C.O.A. 613 (2012); Robin Cheryl Miller, Annotation, Effect of
    38
    Statute Limiting Landowner’s Liability for Personal Injury to Recreational
    User, 
    47 A.L.R. 4th 262
     (1986).             At a minimum, as the caselaw
    demonstrates,    reasonable    minds    can    disagree   as   to   whether   a
    recreational use must be a true outdoor activity.         Reasonable minds
    could also disagree as to whether terms like “nature study” or “other
    summer . . . sports” apply to the facts before us. Plainly, extrinsic aids
    are appropriate tools for us to use in applying the recreational use
    statute to the facts of this case.
    B. Applicability of General Limitations to Iowa Statute.
    1.   Public at large.   In several places, the Iowa statute, like the
    1965 model act, emphasizes that its purpose is to give the public more
    recreational opportunities. In short, it can be argued that the purpose of
    the act itself was to establish quasi-parks on private lands where the
    public would have access in exchange for qualified protection from
    liability and that the statute should be so interpreted. Such an approach
    is consistent with the wording of the statute, the purposes of the act, its
    statutory history, and caselaw in a number of jurisdictions.
    Yet, limiting Iowa’s recreational use statute to lands generally open
    to the public is inconsistent with Peterson. It could be argued that the
    result in Peterson is inconsistent with the statutory purpose.          If the
    statute applied to posted property not open to the public, as Peterson
    suggests, what incentive does it give to a landowner to open his or her
    lands to the public? The purpose of the statute was plainly to increase
    the availability of private lands to public recreation.        To extend the
    statute’s protections to property not open to the public not only fails to
    promote the purposes of the statute, but tends to defeat them. Further,
    the language in Peterson was undercut by subsequent language in Scott,
    where we emphasized that the purpose of the statute was “ ‘a growing
    39
    need for additional recreation areas for use by our citizenry.’ ”        486
    N.W.2d at 42 (quoting H.F. 151, 62d G.A. Reg. Sess. (Iowa 1967)).
    Stare decisis, of course, is a relevant consideration here. Because
    this case can be resolved on other grounds, it is unnecessary to confront
    the question of whether Peterson is good law.
    2. Approach to interpretation of activities covered by Iowa’s
    recreational use statute. There can be no question that the evil sought to
    be addressed by recreational use statutes is the inadequacy of resources
    for outdoor recreation.   The history of the development of recreational
    use statutes, the express language of the ORRRC Report, the 1965 model
    act, and the 1979 proposed model act all point in that direction. The
    reasoning in the cases adopting a true outdoors approach to the
    interpretation of activities covered by recreational use statutes is faithful
    to the language of the Iowa statute and is focused on the evil sought to
    be prevented.
    Nothing in the Iowa statute suggests a different approach. The list
    of recreational uses strongly suggests that the statute is designed to
    protect activities traditionally undertaken outdoors.     While the statute
    recognizes that recreational use immunity may apply to appurtenant
    structures, such immunity for injuries that occur in structures is only
    applicable when the structure itself is part of or incidental to the
    underlying recreational use.     Indeed, although there are hundreds of
    cases involving recreational use immunity, almost none of them occur
    within structures. For those that do, the user was actually engaged in
    the recreational purpose while inside the structure.
    Further, the fact that the legislature has not adopted expansive
    language in its recreational purpose section provides us with a strong
    reason for caution. The legislature clearly has not empowered this court
    40
    to expand or update the list of recreational purposes. The legislature has
    declined to follow the “includes, but is not limited to” language of the
    1965 model act and the even more expansive language of the 1979
    proposed model act. While such an action might be supported by policy
    reasons, any such action must be taken by the legislature, not by us.
    As a result, we conclude that the best interpretation of Iowa’s
    recreational use statute is that the closed universe of activities
    specifically listed in section 461C.2(5) must be interpreted in a fashion
    consistent with promoting true outdoor activity.     With this concept in
    mind, we now turn to the specific language of the Iowa statute to
    determine whether the activity in this case falls within the scope of its
    immunity provision.
    C. Determination of Whether Sallee’s Activities Constitute a
    Recreational Use. As noted above, the legislature has given us a closed
    definition of “recreational purpose.” We thus do not add, or subtract,
    from the legislative definition.   See Gough v. County of Duchess, 
    638 N.Y.S.2d 290
    , 291–92 (Sup. Ct. 1996) (refusing to interpret “hiking” in
    the New York recreational use statute to include an infant’s 500 to 600-
    foot walk through a field); see also Brooks v. Northwood Little League,
    Inc., 
    489 S.E.2d 647
    , 651 (S.C. Ct. App. 1997) (noting that South
    Carolina’s statute, by its express terms, “invites judicial expansion where
    the plain meaning of the statute would not be distorted”).     We do not
    engage in innovations or improvements of the statute.          Rather, we
    interpret it as we find it. See State v. Spencer, 
    737 N.W.2d 124
    , 129–30
    (Iowa 2007). The district court determined Sallee’s claims were barred by
    the recreational use statute because she chaperoned children who
    engaged in horseback riding and nature study. We disagree.
    41
    1. Horseback riding. Like many recreational use statutes, Iowa’s
    definition of “recreational purpose” includes “horseback riding.”      Iowa
    Code § 461C.2(5). However, the mere fact that some of the field trip’s
    activities might qualify as recreational uses does not mean that summary
    judgment was properly granted to the defendant in this case. The issue
    is not whether horseback riding may qualify as a recreational use. The
    issue is more nuanced. Here, Sallee’s injury did not occur while she was
    riding a horse. To be sure, while there was some deposition testimony
    that Sallee “helped with the horse,” there is nothing in the record
    clarifying what that help entailed or indicating that Sallee rode a horse.
    Even assuming Sallee did ride a horse, however, her injury occurred in a
    barn that had no obvious relationship to the horseback riding.        There
    was no claim, for instance, that Sallee’s presence in the barn was
    somehow incident to horseback riding. We agree with the courts that
    have concluded the relevant inquiry is what the plaintiff was doing at the
    time the plaintiff was injured. See, e.g., City of Bellmead v. Torres, 
    89 S.W.3d 611
    , 614 (Tex. 2002); see also Smith v. Ariz. Bd. of Regents, 
    986 P.2d 247
    , 252 (Ariz. Ct. App. 1999) (noting the inquiry is whether the
    plaintiff was engaged in the type of activity contemplated by the statute
    at the time of the injury). At a minimum, there is an issue of material
    fact as to whether the presence of the plaintiff in the barn’s hayloft where
    she was injured was not a necessary incident of horseback riding. In any
    event, the district court erred to the extent it granted summary judgment
    on the basis that Sallee was engaged in horseback riding.
    2. Nature study.     Like horseback riding, nature study is also
    included in the laundry list of recreational purposes under the
    recreational use statute. Iowa Code § 461C.2(5). The Nebraska Supreme
    Court held that looking at livestock at a county fair did not amount to
    42
    nature study under Nebraska’s recreational use statute.         Dykes, 617
    N.W.2d at 823. The court observed that “nature” is defined as “ ‘[a] wild
    condition, untouched by civilization’ ” or “ ‘[t]he elements of the universe,
    such as mountains, plants, planets, and stars.’ ”       Id. at 823 (quoting
    Black’s Law Dictionary 1050 (7th ed. 1999)). Consistent with the history
    of recreational use statutes outlined above, the term “nature study” may
    well include outdoor activities such as bird watching, butterfly
    observation, and the study of pond flora and fauna, but it is difficult to
    characterize frolicking in a hayloft as part of a guided tour of an
    improved barn on a dairy farm as nature study within the meaning of the
    statute. Accordingly, the district court erred to the extent it held that
    Sallee was engaged in nature study at the time of her injury.
    3. Other summer sports.      A number of recreational use statutes
    identify “sports,” “summer sports,” or “other summer sports” as defining
    terms of “recreational purpose.”     Indeed, the 1965 model act included
    “winter sports” as one such defining term. Though the Stewarts did not
    so argue on appeal, there have been suggestions that “other summer . . .
    sports,” as used in section 461C.2(5) includes frolicking in a hayloft. In
    any event, there are compelling reasons as to why frolicking in a hayloft
    is not within the ambit of other summer sports.
    Though commonly a defining term of “recreational purpose,” many
    states do not provide an independent definition of what constitutes these
    sports. Alaska, however, is one state that does. Alaska’s recreational
    use statute includes the phrase “sports or recreational activity” in
    defining its scope.    Alaska Stat. 09.65.202(f)(5) (2012).     The statute
    defines “sports or recreational activity” as:
    a commonly understood sporting activity, whether
    undertaken with or without permission, including baseball,
    softball, football, soccer, basketball, hockey, bungee
    43
    jumping,    parasailing,  bicycling,  hiking,     swimming,
    skateboarding, horseback riding and other equine activity,
    dude ranching, mountain climbing, river floating, whitewater
    rafting, canoeing, kayaking, hunting, fishing, backcountry
    trips, mushing, backcountry or helicopter-assisted skiing,
    alpine skiing, Nordic skiing, snowboarding, telemarking,
    snow sliding, snowmobiling, off-road and all-terrain vehicle
    use.
    Id. § 09.65.290(e)(3)(A).
    The Supreme Court of Montana was called upon to determine
    whether a football-type game called “500” was considered to be a
    recreational purpose under the Montana use statute.         See Kapphan v.
    Vincent, No. DA 09–0182, 
    2009 WL 3764109
    , at *2 (Mont. Nov. 10,
    2009).   Because the Montana statute contains a nonexhaustive list of
    activities defining “recreational purpose” and because one of those
    defining terms is “winter sports,” the court concluded the game was a
    recreational purpose.       Id.   In addition to noting that outdoor hockey
    played on a frozen pond was a winter sport within the ambit of the
    statute, the court noted that “ ‘recreational purpose,’ as commonly
    understood and used in common parlance, would clearly include games
    such as soccer, Frisbee, basketball, football, ‘500,’ or a variety of other
    pursuits.” Id. Similarly, a South Carolina court determined T-ball was a
    “summer sport” within the meaning of the South Carolina statute. See
    Brooks, 489 S.E.2d at 651.
    A Wisconsin appellate court concluded that playing catch with a
    football in a city park was “an outdoor sport or game” under its
    recreational use statute. See Taylor v. City of Appleton, 
    433 N.W.2d 293
    ,
    294 (Wis. Ct. App. 1988).           That court specifically noted that the
    Wisconsin legislature “directed a liberal interpretation of the statute,”
    which states that “recreational activity” means “any outdoor activity
    undertaken for the purpose of exercise, relaxation or pleasure.”        Id.
    44
    (citation and internal quotation marks omitted). The Wisconsin statute
    then lists a number of activities, but includes in that list “any other
    outdoor sport, game, or educational activity.”        Id. (emphasis added)
    (citation and internal quotation marks omitted).      Thus, in addition to
    interpreting the legislative history to require a liberal construction of the
    statute, the statute itself also included catchall language.
    In a related situation, the Supreme Court of Georgia found that
    persons enjoying the Atlanta Olympic Park at the 1996 Summer
    Olympics were engaged in a recreational purpose because the park was
    “created to celebrate the spirit of an historic athletic and cultural event
    and to provide a gathering place for visitors to relax and enjoy
    themselves.”     Anderson, 537 S.E.2d at 348.        However, the Georgia
    statute broadly defines “recreational purposes” using the “includes, but
    is not limited to” language of the 1965 model act. Id. at 347; see also Ga.
    Code Ann.      § 51–3–21(4).   Thus, the court was able to broadly define
    “recreational activity” as “any amusement, play or other form of
    relaxation which refreshes the mind or body.” Anderson, 537 S.E.2d at
    348. Further, the court seemed focused only on whether the property
    was recreational in nature and not whether the user was engaged in a
    recreational purpose while on the property. See id.
    The common thread in these cases and definitions is that “sport,”
    as it is contemplated by recreational use statutes, is narrower than a
    definition meaning merely “a source of diversion” or “physical activity
    engaged in for pleasure.”      See Merriam-Webster’s Collegiate Dictionary
    1134 (10th ed. 2002). Even so, there are further reasons why it is not
    possible to give the definition of “other summer sports” an expansive
    reading outside the context of the other activities mentioned in the
    statute.
    45
    First, when a phrase like “other summer sports” is added to a
    laundry list of terms all of which relate to outdoor activity, we interpret
    “other summer sports” to be similar in character to the other activities,
    all of which relate to outdoor recreation. See Drake ex rel. Drake, 649
    N.E.2d   at   1030      (decorating   an    abandoned   grain   elevator   and
    participating in a haunted house performance was not within statute
    because those activities are inconsistent with general class of behavior
    typified by hunting, fishing, swimming, trapping, camping, hiking, and
    sightseeing). The fancy term for this is ejusdem generis.
    Second, if the term “other summer              sports” simply meant
    pleasurable activity or a source of diversion, then the existing laundry list
    of activities in the statute would become meaningless. They would be
    swallowed up by the new expansive phrase. Further, the amendments
    subsequent to the 1971 addition of the phrase “other summer sports”
    would be entirely superfluous.        See Quesenberry, 317 N.W.2d at 472
    (noting that the addition of “snowmobiling, wood cutting and observation
    tower climbing” to the Wisconsin statute would have been superfluous if
    these activities would have otherwise already been covered under a broad
    interpretation of “recreational uses or purposes” (internal quotation
    marks omitted)). We cannot convert the phrase “other summer sports”
    into a statutory PAC-MAN that goes backward to gobble up preexisting
    statutory limitations and then goes forward to consume subsequent
    legislative language.
    Third, an expansive reading of the term is inconsistent with the
    statutory history.      As noted above, the Iowa legislature, unlike the
    majority of states, has refused to insert potentially expansive language in
    the definition of “recreational purpose.”        The legislature altered the
    language of the 1965 model act and did not adopt the proposals in the
    46
    1979 proposed model act. Accordingly, Sallee did not engage in other
    summer sports as contemplated by the statute.
    4. Summary.       As a result of the above analysis, the activities
    which occurred in the hayloft do not constitute recreational uses under
    the Iowa statute. Further, Sallee’s injuries cannot be characterized as
    resulting from horseback riding, nature study, other summer sports, or
    any other specifically enumerated recreational purpose. As a result, the
    district court erred in granting summary judgment for the defendants
    based on the limited immunity provided in Iowa’s recreational use
    statute.
    VIII. Willful or Malicious Conduct.
    Section      461C.6(1)    provides     that   any   immunity   under   the
    recreational use statute does not extend to “willful or malicious failure to
    guard or warn against a dangerous condition, use, structure, or activity.”
    Iowa Code § 461C.6(1).         Sallee claims the record in this case raises a
    genuine issue of material fact as to whether this exception applies.
    Because Sallee does not claim the Stewarts acted maliciously, the only
    question is whether there is a triable issue on whether the Stewarts
    acted willfully.
    We considered the question of what amounted to willful failure to
    guard against a dangerous condition under the recreational use statute
    in a per curiam decision in Bird v. Economy Brick Homes, Inc., 
    498 N.W.2d 408
     (Iowa 1993).          In that case, the defendant erected a steel
    cable across an access road to prevent vehicles from entering the
    property.   Bird, 498 N.W.2d at 408.           While we recognized a split in
    authority on the issue, we held that the placement of the steel cable,
    without more, did not amount to a willful failure to guard against a
    dangerous condition. Id. at 410. Because it was a per curiam decision,
    47
    we did not engage in extensive analysis of the meaning of “willful” and we
    did not adopt a specific standard for determining precisely what kind of
    conduct amounted to willful under the recreational use statute.
    In any event, Bird is a dangerous condition case.         There is no
    suggestion in Bird that the defendant was present when the plaintiff
    drove his motorcycle down the access road and failed to warn of the
    cable across the road. The case might well have had a different outcome
    if the defendant had an opportunity to warn Bird of the dangers posed by
    a cable across the road, but failed to do so.
    We now turn to other authorities.         One leading authority states
    that willful conduct may be found under a recreational use statute only
    where “a known or obvious risk so great as to make it highly probable
    that harm will result.” 3 Louis A. Lehr, Jr., Premises Liability 3d, § 54.41
    (2012).   In Mandel v. United States, the Eighth Circuit indicated that
    willfulness requires knowledge or an appreciation that “danger is likely to
    result.” 
    719 F.2d 963
    , 967–68 (8th Cir. 1983). In construing the related
    phrase “willful and wanton,” we have stated that the actor must show
    “ ‘disregard of a known or obvious risk that was so great as to make it
    highly probable that harm would follow.’ ” Brokaw v. Winfield–Mt. Union
    Cmty. Sch. Dist., 
    788 N.W.2d 386
    , 396 (Iowa 2010) (quoting McClure v.
    Walgreen Co., 
    613 N.W.2d 225
    , 230 (Iowa 2000)).
    We conclude that the plaintiff has not presented sufficient evidence
    to allow a reasonable fact finder to find that defendants acted willfully.
    The defendants knew that Sallee was a very large woman.            There is
    insufficient evidence in the record, however, to support a finding that
    Sallee would likely sit or stand on the hay bales covering the hole in the
    loft or that it was highly probable that the hay bales would almost
    assuredly collapse as a consequence, thereby causing serious injury.
    48
    IX. Conclusion.
    We hold the limited immunity provided by the recreational use
    statute does not apply in this case. We further conclude, however, that
    the plaintiff has not raised a triable issue of willful or malicious conduct.
    As a result, the decision of the district court is reversed and the case is
    remanded for further proceedings.
    DECISION OF COURT OF APPEALS VACATED; DISTRICT
    COURT JUDGMENT REVERSED, AND CASE REMANDED.
    All justices concur except Wiggins, J., who concurs specially and
    Waterman and Mansfield, JJ., who dissent.
    49
    #11–0892, Sallee v. Stewart
    WIGGINS, Justice (concurring specially).
    I concur with the majority opinion.      I write separately, however,
    because, under the facts of this case, I would find the plaintiffs were
    entitled to a trial in the event the immunity provided by the recreational
    use statute applied to the activity of children playing in a barn’s hayloft.
    For the reasons expressed below, I believe the Sallees’ claim of negligent
    supervision is outside the scope of the statute’s immunity and thus, is
    an independent basis for seeking recovery from the Stewarts.
    I. Relationship Between Negligent Supervision and Premises
    Liability Claims.
    We have one case that considers the relationship between
    negligence claims and the immunity accorded in Iowa’s recreational use
    statute. In Scott v. Wright, the plaintiff was injured when she fell off and
    then was pinned under a hay wagon during a hayride on the defendants’
    property. 
    486 N.W.2d 40
    , 41 (Iowa 1992). The plaintiff sought to recover
    on a theory of vicarious liability for the driver’s negligent operation of the
    tractor. Scott, 486 N.W.2d at 42. After a verdict for the plaintiff, the
    defendants appealed, claiming the recreational use statute immunized
    the defendants from suit and accordingly, barred the plaintiff’s recovery.
    Id. at 41–42.
    There, we declined to disturb the jury verdict. Id. at 42. A review
    of the statute’s legislative history revealed that nothing in the language of
    the recreational use statute “suggests a legislative intent to immunize all
    negligent acts of landowners, their agents, or employees.”           Id.   We
    emphasized the statute was enacted to serve “ ‘a growing need for
    additional recreation areas for use by our citizenry.’ ” Id. (quoting H.F.
    151 62d G.A., Reg. Sess., explanation (Iowa 1967)).         Accordingly, our
    50
    holding was also based upon the following practicality: “The public’s
    incentive to enter and enjoy private agricultural land would be greatly
    diminished if users were subject, without recourse, to human error as
    well as natural hazards.” Id.
    In focusing the scope of the statute so narrowly, we emphasized
    that the language of the recreational use statute “is couched in terms of
    premises liability.” Id. (emphasis added). In short, the test announced in
    Scott is whether the claim is based upon “human error” or “natural
    hazards.” Id. If the claim involves natural hazards, the immunity in the
    recreational use statute applies and bars the plaintiff’s claim, which
    subsequently extinguishes any premises liability claims. However, if the
    claim arises from human error, the recreational use statute provides no
    immunity.
    In addition to Scott, we have had at least one other occasion to
    consider the interplay between claims involving negligent supervision
    and claims for premises liability. In Sweeney v. City of Bettendorf, we
    considered whether the City was liable for negligently supervising a child
    who was injured by a flying bat at a city-sponsored trip to a baseball
    game. 
    762 N.W.2d 873
    , 875–76 (Iowa 2009). We recognized that under
    the applicable precedent, the plaintiffs had no premises liability claim
    against the baseball stadium’s owner or operator. Sweeney, 762 N.W.2d
    at 882–83. However, the plaintiffs still had a negligence claim against
    the City.   Id. at 883.   To reach this conclusion, we stated that “a
    negligent supervision case is fundamentally different than a case
    involving premises liability.”   Id. at 882.   We emphasized the claim
    against the City “does not relate to the instrumentality of the injury, but
    instead focuses on the proper care and supervision of children in an
    admittedly risky environment.” Id.
    51
    In Sweeney, we approvingly cited the case, Cook v. Smith, 
    33 S.W.3d 548
     (Mo. Ct. App. 2000). See Sweeney, 762 N.W.2d at 883. In
    Cook, the plaintiff was invited to the defendants’ farm for a party. 33
    S.W.3d at 551.       While there, the plaintiff rode an ATV and was
    subsequently injured.     Id.   The plaintiff brought a two-count action
    against the defendant landowners, alleging premises liability and
    negligent supervision.    Id.   The court dismissed the premises liability
    claim, but allowed the negligence claim to go forward, thereby
    demonstrating the different theoretical bases for premises liability and
    negligence. Id. at 552–55.
    II. Viability of Plaintiffs’ Negligence Claim.
    The question then is whether the defendants were entitled, as a
    matter of law, to summary judgment on the plaintiffs’ negligence claim
    under the facts presented in this case.
    In order to support a claim of negligence, there must be some kind
    of duty owed to the plaintiff. See, e.g., Doe v. Cent. Iowa Health Sys., 
    766 N.W.2d 787
    , 792 (Iowa 2009) (recognizing a duty may arise pursuant to a
    statutory enactment). The court of appeals found the Stewarts owed a
    duty to Sallee, based upon the Stewarts’ affirmative action of providing a
    guided barn tour.
    The analytical approach used by the court of appeals in reaching
    this conclusion is sound because the Stewarts wear two hats in this
    case.    One hat is that of landowners.     The other hat is that of tour
    guides. Although the Stewarts have immunity as landowners under the
    recreational use statute if the activity resulting in Sallee’s injury had a
    recreational purpose, the statute has no impact whatsoever on the
    distinctly different question of whether the Stewarts owed a duty of care
    when they guided the barn tour.
    52
    This is true because the immunity provided by Iowa Code section
    461C.3 is limited to premises liability claims. The immunity provision
    specifies that “an owner of land” has no duty “to keep the premises safe”
    or warn of dangerous conditions, uses, structures, or activities “on such
    premises.” Iowa Code § 461C.3 (2009). Surely we all recognize this as
    classic premises liability language.
    Here, however, the Sallees have a negligence claim that is
    independent of premises liability.     The Sallees have stated a cause of
    action based upon the acts or omissions of the Stewarts as supervisors of
    the barn tour. This claim differs from premises liability, which is passive
    because a landowner who does nothing can be liable based on a failure
    to act. Here, the Stewarts covered the hay drop and directed Sallee to
    the hayloft.
    The Sallees’ negligence claim is supported by the Restatement
    (Second) of Torts section 324A (1965), which provides that one may be
    liable for harm to another if he or she gratuitously undertakes “to render
    services to another which he [or she] should recognize as necessary for
    the protection of a third person . . . if his [or her] failure to exercise
    reasonable care increases the risk of such harm.” To give the claim a
    shorthand name, it is a negligent supervision claim. We have imposed
    liability for such claims under the rule contained in section 324A. See,
    e.g., Craven v. Oggero, 
    213 N.W.2d 678
    , 682 (Iowa 1973) (holding a
    supervisor who assumes the obligation to provide a safe place for an
    employee can be held liable under section 324A); Fabricius v. Montgomery
    Elevator Co., 
    254 Iowa 1319
    , 1325–28, 
    121 N.W.2d 361
    , 364–66 (1963)
    (imposing liability for negligent inspection gratuitously undertaken by an
    insurance company).
    53
    The distinction I draw between premises liability and negligent
    supervision claims is generally recognized in the case law. See Raburn v.
    Wal-Mart Stores, Inc., 
    776 So. 2d 137
    , 139–41 (Ala. Civ. App. 1999)
    (noting that while an owner may not have an initial duty to prevent
    injuries to business invitees as a result of criminal acts, liability may
    result from negligent performance of a voluntary undertaking to
    apprehend criminals); Redinger v. Living, Inc., 
    689 S.W.2d 415
    , 417 (Tex.
    1985) (recognizing a duty to keep a premises safe can subject a general
    contractor to liability for negligence in cases “arising from a premises
    defect” or “those arising from an activity or instrumentality”); see also
    Sidwell v. Griggsville Cmty. Unit Sch. Dist. No. 4, 
    588 N.E.2d 1185
    , 1188–
    89 (Ill. 1992) (deciding a case mirroring the facts here, where the court
    found a limited immunity statute barred claims of negligent supervision
    against teachers, but did not bar premises liability claims against the
    school district).
    Perhaps more importantly, the distinction between negligent
    supervision and premises liability is widely recognized across the
    jurisprudential landscape of recreational use statutes. For instance, in
    LePoidevin v. Wilson, the Wisconsin Supreme Court distinguished a
    premises liability claim, which was subject to an immunity defense
    under Wisconsin’s recreational use statute, from a negligence claim
    arising from the landowner’s son taunting the plaintiff into diving
    headfirst into a three-foot-deep pond.    
    330 N.W.2d 555
    , 559–62 (Wis.
    1983). Similarly, in Klein v. United States, the California Supreme Court
    found that a recreational use statute did not extinguish claims arising
    from the negligent acts of owners on the premises. 
    235 P.3d 44
    , 47–53
    (Cal. 2010). In Dickinson v. Clark, the court noted that a recreational use
    statute did not apply to a claim related to the landowner’s negligent
    54
    supervision of a minor operating a log splitter. 
    767 A.2d 303
    , 305–06
    (Me. 2001). Finally, in Sena v. Town of Greenfield, the court found that a
    city could be held liable for sledding injuries, where the city actually
    supervised   the    activity,   notwithstanding   potential   coverage   by   a
    recreational use statute. 
    696 N.E.2d 996
    , 999–1000 (N.Y. 1998). Thus,
    even though a recreational use statute may bar a plaintiff’s claim based
    upon premises liability, the plaintiff may still have a viable claim against
    the defendant under the theory of negligent supervision.
    To determine whether a plaintiff has a viable claim of negligent
    supervision, the court must look to the level of control the defendant
    exercised over the plaintiff’s activity. In Cohen v. Heritage Motor Tours,
    Inc., the court found a tour guide assumed a duty by instructing
    participants to cross a stream in a particular manner. 
    618 N.Y.S.2d 387
    ,
    389 (App. Div. 1994). This voluntarily assumed duty, of course, was not
    related to any potential premises liability claim that the plaintiff might
    have asserted against the landowner. Similarly, in Gordon v. Muchnick,
    the court found a jury question was raised as to whether the defendant
    assumed an undertaking sufficient to give rise to a duty of care, where
    the defendant guided the plaintiff across a street. 
    579 N.Y.S.2d 745
    , 745
    (App. Div. 1992).
    In short, the court of appeals got it right on this issue. The Sallees
    have   stated   a   claim   based    upon   negligent   supervision   that    is
    independent of their cause of action for premises liability. As a result,
    even if the immunity in the recreational use statute covered the activity
    of playing in a hayloft and precluded recovery, the Stewarts’ affirmative
    conduct raises another claim outside the scope of the statute and
    presents a triable issue not subject to summary judgment.
    55
    #11–0892, Sallee v. Stewart
    MANSFIELD, Justice (dissenting).
    Sometimes two acts of generosity collide and lead to an
    unfortunate result. That is what happened in this case. Matthew and
    Diana Stewart invited a kindergarten class to visit their dairy farm on a
    field trip. Kimberly Sallee volunteered her time to serve as a chaperone
    for the visit. While Sallee was accompanying the children during their
    playtime in a hayloft, she fell through a chute that was covered by hay
    bales and broke her wrist and ankle. Sallee sued the Stewarts for her
    injuries.   The Stewarts answered and asserted Iowa’s recreational use
    immunity, Iowa Code §§ 461C.1–.8 (2009), which limits the liability of
    landowners who allow others to use their premises without charge for
    recreational purposes.
    Sallee argued for several reasons that the immunity did not apply.
    The district court disagreed and granted summary judgment to the
    Stewarts.     I would affirm the district court for the reasons set forth
    herein.
    While I believe the majority opinion displays the usual scholarship
    characteristic of its author, it suffers from conceptual flaws.             In
    particular,   it   overemphasizes   what    other   states   have   done   and
    underemphasizes what Iowa has done. As my colleagues acknowledge,
    when we get to the critical provisions involved in this case, Iowa’s
    recreational use law is largely sui generis.        Therefore, I believe it is
    important to focus on the evolution of our law. Iowa’s recreational use
    statute, from the very outset, was designed to encourage farmers to offer
    free recreational use of their lands and appurtenant buildings. It turns
    this law upside down to hold that jumping in a hayloft during a
    gratuitous field trip was not such a use.
    56
    I. Iowa’s Recreational Use Law.
    As first enacted in 1967, Iowa’s statute was limited to private
    agricultural     lands   and   “buildings,   structures   and   machinery    or
    equipment appurtenant thereto.” 1967 Iowa Acts ch. 149, § 2. Thus, the
    original definition of “land” covered by the act read as follows:
    “Land” means land used for agricultural purposes, including
    marshlands, timber, grasslands and the privately owned
    roads, water, water courses, private ways and buildings,
    structures and machinery or equipment appurtenant
    thereto.
    Id. Accordingly, from the very beginning, our general assembly sought to
    protect agricultural lands as well as “buildings, structures and
    machinery or equipment” that were “appurtenant thereto,” such as a
    barn. Id.
    Meanwhile, the legislature’s original, unique-to-Iowa definition of
    “recreational purpose” read as follows:
    “Recreational purpose” means the following or any
    combination thereof: hunting, fishing, swimming, boating,
    camping, picnicking, hiking, pleasure driving, nature study,
    water skiing, winter sports, and viewing or enjoying
    historical, archeological, scenic, or scientific sites while going
    to and from or actually engaged therein.
    Id.
    In 1971, the legislature added “horseback riding” to the list of
    approved recreational purposes. 1971 Iowa Acts ch. 129, § 1. Later in
    the same session, the legislature expanded the definition of “recreational
    purpose”    to   include   “motorcycling”    and   “snowmobiling,”   while   it
    substituted the phrase “other summer and winter sports” for “winter
    sports.” Id. ch. 130, § 1. Although we do not have helpful legislative
    history for the second 1971 amendment, it seems logical to conclude that
    the legislature wanted to obviate the need for future piecemeal
    57
    amendments by including some kind of a catchall—other summer and
    winter sports.
    In 1978, the legislature expanded the definition of “land” to include
    “abandoned or inactive surface mines” and “caves,” in addition to “land
    used for agricultural purposes.” 1978 Iowa Acts ch. 1066, § 1. In 1988,
    the legislature added “trapping” to the list of covered “recreational
    purposes.” 1988 Iowa Acts ch. 1216, § 46.
    In 2006, the general assembly inserted the phrase “or urban deer
    control” where it appears in the current version of the statute. See 2006
    Iowa Acts ch. 1121, §§ 1, 4, 5. Simultaneously, the legislature greatly
    expanded the previous definition of “land.” Id. § 2. Until then, as noted,
    only certain categories of land had been covered, one of those categories
    being agricultural land. The 2006 legislation inserted the phrase “private
    land located in a municipality including,” essentially bringing all private
    land within the scope of the statute. Id.10 A final amendment, in 2012,
    added “all-terrain vehicle riding” within the definition of “recreational
    purpose.” See 2012 Iowa Acts ch. 1100, § 58.
    We have previously referred to chapter 461C as “a blanket
    abrogation of duty to all recreational users (except as provided in section
    [461C.6]).”    Peterson v. Schwertley, 
    460 N.W.2d 469
    , 471 (Iowa 1990)
    (finding that the statute barred a claim brought by a young man who had
    trespassed on the defendant’s property to go swimming and was
    paralyzed by a fall).
    10Presumably,  the legislature decided to broaden the definition of “land” in 2006
    when it added “urban deer control” to the protected purposes because controlling the
    urban deer population would require entry onto properties that did not fit the earlier,
    narrower definition of “land.” The enrolled bill was entitled, “An act allowing private
    landowners limited immunity from premises liability during urban deer control hunts.”
    2006 Iowa Acts ch. 1121.
    58
    II. Does the Immunity Apply to the Stewarts’ Barn?
    The first question to be answered is whether the Stewarts’ dairy
    barn is the kind of property to which the recreational use immunity can
    apply.     I think the answer is clear from the statute.      The statutory
    immunity extends to “buildings” and “structures,” see Iowa Code
    § 461C.2(3), so long as they are “appurtenant” to a category of “land” that
    is covered by the statute, see id.         The statute nowhere requires an
    outdoor use, and indeed the reference to buildings is inconsistent with
    such a restriction.
    It is true that courts in other jurisdictions have reached differing
    conclusions as to the kinds of properties that are covered by their
    respective recreational use laws. As one court has said, “[W]e observe a
    widespread conflict among the jurisdictions as to exactly what type of
    land is intended to be covered by the liability limitation.”     Redinger v.
    Clapper’s Tree Serv. Inc., 
    615 A.2d 743
    , 745 (Pa. Super. Ct. 1992). Thus,
    the Pennsylvania Supreme Court has held that an indoor swimming pool
    is not covered. Rivera v. Phila. Theological Seminary, 
    507 A.2d 1
    , 8 (Pa.
    1986) (stating that the legislature intended to limit buildings, structures,
    machinery, or equipment to “ancillary structures attached to open space
    lands made available for recreation”).       The Louisiana Supreme Court
    concluded that an outdoor swimming pool was not covered. Keelen v.
    State, 
    463 So. 2d 1287
    , 1290 (La. 1985) (stating that “when the
    instrumentality . . . is of the type usually found in someone’s backyard,
    then the statutes afford no protection”).         On the other hand, the
    Massachusetts Supreme Judicial Court has found that the immunity
    applies to an indoor gymnasium. Seich v. Town of Canton, 
    686 N.E.2d 981
    , 983 n.5 (Mass. 1997). And the Ninth Circuit has held that Hawaii’s
    act covers urban swimming pools. See Palmer v. United States, 
    945 F.2d 59
    1134, 1135–36 (9th Cir. 1991). But see Cassio v. Creighton Univ., 
    446 N.W.2d 704
    , 711 (Neb. 1989) (holding that Nebraska’s act does not apply
    to independent indoor recreational facilities, including swimming pools).
    Given this divergence of views, I think it is most helpful to look at what
    we did here in Iowa.
    When our general assembly enacted Iowa’s recreational use
    immunity law in 1967, it modified the proposed model act’s definition of
    “land.” The model act stated:
    “Land” means land, roads, water, watercourses, private ways
    and buildings, structures, and machinery or equipment
    when attached to the realty.
    Council of State Governments, Public Recreation on Private Lands:
    Limitations on Liability, 24 Suggested State Legislation 150, 151 (1965)
    [hereinafter Council of State Governments].      However, our legislature
    chose the following language:
    “Land” means land used for agricultural purposes, including
    marshlands, timber, grasslands and the privately owned
    roads, water, water courses, private ways and buildings,
    structures and machinery or equipment appurtenant
    thereto.
    1967 Iowa Acts ch. 149, § 2.
    Thus, from the outset, our legislature made a decision that Iowa
    would go its own way and have an immunity directed to agricultural
    properties. The general assembly stated that the immunity would cover
    agricultural land “and buildings, structures and machinery or equipment
    appurtenant thereto.”    Id.    Hence, the legislature expressly included
    buildings, so long as they were appurtenant.      Black’s Law Dictionary
    defines “appurtenant” to mean “[a]nnexed to a more important thing.”
    Black’s Law Dictionary 118 (9th ed. 2009). Therefore, a barn that is part
    60
    of a substantial farm operation like the Stewarts’ qualifies as an
    appurtenant building.
    My colleagues raise the concern that Iowa’s recreational use
    immunity could possibly lead to strange results, such as coverage for a
    backyard barbecue.         But this concern, to the extent it exists, follows
    largely from the legislature’s 2006 expansion of the definition of “land” as
    part of its urban deer control amendment. This is not a reason to deny
    the Stewarts’ immunity for activities in an agricultural building that
    always has been covered by the statute.11
    Alternatively, my colleagues suggest that because the Stewarts
    only allowed a few, specified groups on their farm, it was not open to the
    public and the recreational use immunity does not apply. This too is a
    misreading of the statute, which contains no such qualification. Section
    461C.3 provides there is no duty owed to “others” who enter or use the
    property for recreational purposes. Section 461C.4 covers “any person”
    who is invited or allowed to use the property for recreational purposes.
    Significantly, we found that Iowa’s recreational use immunity applied in
    Peterson even though the landowner had posted no trespassing signs
    and thus the property was not open to the general public. 460 N.W.2d at
    470–71. As we explained:
    That statute [what is now section 461C.3] simply refers to
    recreational use by “others.” We believe the word “others”
    embraces all persons other than the landowner who makes
    such use of the property.
    11My  colleagues assert that a building, to be covered, must be appurtenant to a
    recreational use in the “true outdoors.” This is the majority’s gloss on the statute. It is
    not what the legislature enacted. The legislature required that the building be
    appurtenant to the land, not to the recreational use, let alone to an outdoor recreational
    use. See Iowa Code § 461C.2(3). As noted by the court of appeals, “The Stewarts’ dairy
    farm and appurtenant buildings qualify for limited liability by this definition.”
    61
    Id. at 471.     Although my colleagues call into question the continued
    vitality of Peterson, there is no justification for doing so. This precedent
    is twenty-two years old, and the legislature in 2006 made a substantial
    modification of the statute without disturbing it. In any event, the case
    was correctly decided.
    As the Missouri Supreme Court has said, in a case holding that a
    farmer who allowed two turkey hunters onto his property free of charge
    could assert the same immunity:
    The use of the term “public” merely reflects the fact
    that the statute is designed to encourage landowners with
    property suitable for certain recreational activities to allow
    members of the public to participate in those activities.
    Nowhere does the [Missouri statutory recreational use
    immunity] require that land be opened to the entire general
    public, and this Court will not add language to a statute that
    is clear and unambiguous.
    State ex rel. Young v. Wood, 
    254 S.W.3d 871
    , 873 (Mo. 2008); see also
    Howard v. United States, 
    181 F.3d 1064
    , 1071 (9th Cir. 1999) (“The
    [Hawaii    recreational     use    immunity      statute]    does    not   contain     a
    requirement that a landowner allow each and every individual of the
    general public access and use of the land . . .”); Holden v. Schwer, 
    495 N.W.2d 269
    , 274 (Neb. 1993) (“[I]n order to facilitate the purpose of [the
    Nebraska recreational use immunity statute] a landowner need allow
    only some members of the public, on a casual basis, to enter and use his
    land for recreational purposes to enjoy the protection of the act.”).12
    I recognize that some other jurisdictions have ruled otherwise. See
    Hall v. Henn, 
    802 N.E.2d 797
    , 799–800 (Ill. 2003) (holding that Illinois’s
    12Because   sections 461C.3 and 461C.4 of Iowa’s act are identical to the model
    act—save for Iowa’s addition of “urban deer control” and substitution of “holder of land”
    for “owner of land”—I believe that out-of-state cases are more relevant here. Compare
    Iowa Code §§ 461C.3, .4, with Council of State Governments, 24 Suggested State
    Legislation at 151.
    62
    recreational use immunity statute does not apply to “landowners who
    restrict the use of their property to invited guests only”); Loyer v.
    Buchholz, 
    526 N.E.2d 300
    , 302 (Ohio 1988) (holding that Ohio’s statute
    “does not extend to private owners of residential swimming pools whose
    social guest is injured while swimming, where the premises in question
    are not held open for gratuitous recreational use by the general public”);
    Perrine v. Kennecott Mining Corp., 
    911 P.2d 1290
    , 1293 (Utah 1996)
    (holding that “to qualify for immunity under [Utah’s statute], landowners
    must make their land available to all members of the general public”).
    But these courts have done so on the basis that this limitation is
    necessary   because   those   state   statutes   would   otherwise   provide
    immunity for homeowners from negligence claims brought by social
    guests who enter for recreational purposes. See Hall, 802 N.E.2d at 800
    (stating that “defendant’s reading of the Act, while textually plausible,
    renders an absurd and unjust result”); Loyer, 526 N.E.2d at 302; Perrine,
    911 P.2d at 1293. I do not believe we are at liberty to rewrite the statute,
    at least where the result in this case is not absurd or unjust. Farmers
    who allow school groups, but not every member of the general public, to
    enjoy their property for recreational purposes, are still entitled to the
    benefit of the statute if the other requirements of the immunity have
    been met.
    III. Was Sallee Engaged in a Recreational Purpose?
    My colleagues conclude that the immunity should not apply
    because the excursion to the hayloft was not a recreational purpose. I
    disagree.
    The Stewarts contended that the Sacred Heart kindergarten field
    trip potentially involved three activities specifically identified in Iowa’s
    statute: “horseback riding, . . . nature study, . . . other summer and
    63
    winter sports.” Iowa Code § 461C.2(5). I believe the third category is
    dispositive of this case.     As noted, this part of Iowa’s statute is
    distinctive. To my knowledge, no other state’s definition of “recreational
    purpose” uses the same “other summer and winter sports” terminology.
    Therefore, out-of-state cases are of limited value.
    The term “sport” has a number of definitions.            For example,
    Merriam-Webster’s Collegiate Dictionary defines sport as “a source of
    diversion: RECREATION,” and “physical activity engaged in for pleasure,”
    among other things. See Merriam-Webster’s Collegiate Dictionary 1134
    (10th ed. 2002).
    In City of Marion v. Iowa Department of Revenue & Finance, we held
    that the department could tax municipal swimming pool admission fees
    on the theory that these were “fees paid to cities and counties for the
    privilege of participating in any athletic sports.” 
    643 N.W.2d 205
    , 206–
    08 (Iowa 2002).    There, we upheld the department’s interpretation of
    “athletic sports” as including recreational swimming. City of Marion, 643
    N.W.2d at 207.     The agency had specifically defined a “sport” as “any
    activity or experience which involves some movement of the human body
    and gives enjoyment or recreation.” Id.
    On the other hand, a federal district court recently observed that
    “it is not clear that snorkeling falls within the plain meaning of ‘sports,’ ”
    relying on other dictionary definitions that require a “sport” to be
    governed by “form,” “rules,” or “customs.” Hawaiian Isle Adventures, Inc.
    v. N. Am. Capacity Ins. Co., 
    623 F. Supp. 2d 1189
    , 1197–98 (D. Haw.
    2009).
    As I have noted, the “other summer and winter sports” language
    was part of a 1971 amendment where the legislature also added
    “motorcycling” and “snowmobiling” to the list of covered activities. 1971
    64
    Iowa Acts ch. 130, § 1. I think that by doing so, the legislature opted for
    a broader definition of “sports”—similar to the one we upheld in City of
    Marion—rather than a definition limited to contests governed by forms,
    rules, or customs. By using the word “other,” the legislature implied that
    items previously listed in the definition, and particularly motorcycling
    and snowmobiling which were being added, were also sports. See, e.g.,
    State v. Ashland, 
    259 Iowa 728
    , 730, 
    145 N.W.2d 910
    , 911 (1966)
    (stating that “[t]he naming of pistols and revolvers followed by the words
    ‘other dangerous weapon’ clearly designates the listed items as
    dangerous weapons by statute”). Those activities would be considered
    sports only under a broad definition that equated a sport with a form of
    play or diversion. Snowmobiling is a sport in the sense that it is a form
    of physical activity engaged in for pleasure, not in the sense that it is a
    contest governed by forms, rules, or customs, like baseball or ice hockey.
    This interpretation would not have led to awkward results at the
    time, because in 1971 only agricultural lands and appurtenant
    buildings, structures, machinery, and equipment were covered. In short,
    I conclude the legislature intended in 1971 to introduce some flexibility
    into the definition of “recreational purpose” that other states (which used
    the model act language) already had.               In short, while our general
    assembly had elected not to use the model act’s broader phrasing—
    “includes, but is not limited to”—in 1967, it nonetheless opened up the
    definition of “recreational purpose” in 1971 by making clear that other
    summer and winter sports would be covered.13
    13The majority contends that construing “other summer and winter sports” as
    some kind of a catchall is inconsistent with the fact that the legislature later added
    trapping and all-terrain vehicle riding to the list of covered activities in section
    461C.2(5). But the majority’s own construction of “other summer and winter sports” as
    meaning “true outdoor sports” is subject to the same criticism. I think we should
    acknowledge the reality that groups often go to the legislature seeking a specific
    65
    Under a dictionary definition where “sport” means “a source of
    diversion: RECREATION” and “physical activity engaged in for pleasure,”
    jumping in a hayloft clearly qualifies as a sport. See Merriam-Webster’s
    Collegiate Dictionary 1134 (10th ed. 2002). It is true that the activities
    specifically identified in section 461C.2(5) are normally outdoor activities,
    but the legislature did not say that sports would only be covered when
    played outdoors. Frolicking in hay can be and frequently is an outdoor
    sport. The definition of “land” covers buildings that are appurtenant to
    covered land, and the inclusion of buildings would not have made sense
    if the legislature did not mean some indoor activities to be covered by the
    statute.14
    Alternatively, my colleagues suggest that even if the children were
    embarked on a recreational purpose on May 18, 2010, Sallee was not. In
    other words, chaperoning a recreational activity is not itself a
    recreational purpose. However, it is sufficient in my view that Sallee was
    present to help with the class’s recreational activity. For example, the
    Hawaii Supreme Court has found that the recreational use immunity
    applied to the claim of a paid scuba instructor who was injured while
    leading clients across hotel property after a dive. Thompson v. Kyo-Ya
    Co., 
    146 P.3d 1049
    , 1057–58 (Haw. 2006). As the court put it, “[W]here
    the plaintiff’s presence on the land is closely associated with the
    presence of individuals whose purpose on the land is purely recreational,
    ____________________________
    statutory immunity even when a more general immunity already protects them. The
    important point here is that the majority’s construction of “sports” is consistent with
    neither of the two common definitions of that term.
    14Recognizing  the fact that the statute does cover buildings, my colleagues
    concede that “under some circumstances activities within a building might give rise to
    immunity under the statute.” Thus, they would presumably find that horseback riding
    inside a covered enclosure on a farm would be subject to the recreational use immunity.
    But why not jumping in a hayloft?
    66
    the recreational purpose attaches to the plaintiff.” Id. at 1058. Quoting
    the trial court in that case, the court concluded that the plaintiff was
    “engaged in ‘an activity in pursuit of the use of the property for
    recreational purposes.’ ” Id.; see also Palmer, 945 F.2d at 1137–38
    (rejecting a grandparent’s argument that he was not engaged in
    “recreation” because he was supervising his grandchildren who were
    swimming); Ornelas v. Randolph, 
    847 P.2d 560
    , 564 (Cal. 1993) (stating
    that “whether plaintiff entered the property to play on the equipment, or
    merely accompanied the other children at play, is immaterial”); Hafford v.
    Great N. Nekoosa Corp., 
    687 A.2d 967
    , 968–69 (Me. 1996) (holding that
    Maine’s recreational use statute applied to an outfitter who was injured
    while supplying canoeing and camping enthusiasts); Fetherolf v. State,
    
    454 N.E.2d 564
    , 565–66 (Ohio Ct. App. 1982) (finding as a matter of law
    that the plaintiff who was injured while walking toward the beach with
    his three-year-old daughter was a recreational user, even though his
    shoulder injury prevented him from doing anything other than sitting
    and watching while his family swam). But see Rintelman v. Boys & Girls
    Clubs of Greater Milwaukee, Inc., 
    707 N.W.2d 897
    , 904–06 (Wis. Ct. App.
    2005) (finding that a chaperone was not engaged in a recreational activity
    when she fell moving from one building to another at a weekend
    retreat).15
    Iowa’s statute applies when there is an “entry or use by others for
    recreational purposes.”        Iowa Code § 461C.3.           It applies to “persons
    entering for such purposes.” Id. Simply stated, this language does not
    require that each person herself be enjoying the recreational activity so
    15Here again, we are interpreting provisions (relevant portions of sections 461C.3
    and 461C.4) that match the model act, so I believe out-of-state authorities are entitled
    to more weight than they otherwise would be. Compare Iowa Code §§ 461C.3, .4, with
    Council of State Governments, 24 Suggested State Legislation at 151.
    67
    long as her presence on the property is in furtherance of a recreational
    purpose. It would be a strange result if a farmer could let six-year-olds
    on his property for fun and enjoyment but had to shoo their adult
    chaperones away to avoid legal liability.
    IV. Does the Record Raise an Issue of a Willful or Malicious
    Failure to Guard or Warn Against a Dangerous Condition?
    Section 461C.6 removes any “willful or malicious failure to guard
    or warn against a dangerous condition, use, structure, or activity” from
    the scope of the recreational use immunity. Sallee argues that she raised
    a genuine issue of material fact as to whether this exception applies,
    even if the Stewarts would otherwise be entitled to a recreational use
    immunity. The district court and the court of appeals disagreed, as do
    the majority and I.
    This court has addressed this statutory provision once before. See
    Bird v. Economy Brick Homes, Inc., 
    498 N.W.2d 408
    , 409 (Iowa 1993). In
    Bird, a motorcyclist struck a steel cable that had been placed across an
    access road.   Id. at 408.    “At the time of the accident, there were no
    markings on the cable to keep it from blending with its surroundings.”
    Id.   After discussing various other cases that had interpreted similar
    language, we concluded that the mere placement of an unmarked cable
    across an access road “did not create an issue of material fact as to
    whether Economy acted willfully or maliciously.” Id. at 410.
    The Stewarts had been allowing this kindergarten class to come for
    the past twenty-five years. During that entire time, the chute had been
    present in the hayloft.    There is no evidence there had ever been an
    accident in the hayloft.     “It’s never been a concern,” Matthew Stewart
    testified. The Stewarts insisted on being personally present for any visits
    by any groups. Matthew Stewart explained both the reason why there
    68
    was a chute in the loft (to allow hay to be thrown down occasionally), and
    the reason why the chute was covered (to keep the animals warmer).
    This case does not fit within the circumstances where a willful or
    malicious failure to warn or guard has been found. In Mandel v. United
    States, cited by Sallee, the plaintiff was paralyzed from diving onto a
    submerged rock. 
    719 F.2d 963
    , 964–65 (8th Cir. 1983). Although the
    park rangers did not know of this specific rock, they knew of submerged
    rocks in the vicinity, knew that people swam there, and had brochures
    which warned people to be careful about diving; yet they failed to warn
    the plaintiff or post signs and instead told the plaintiff “that is where
    everybody goes and that is where we recommend for you to go.” Mandel,
    719 F.2d at 967. “It could reasonably be inferred and found that such
    conduct is the commission of an act with knowledge or appreciation that
    danger is likely to result therefrom.” Id. at 968; see also 3 Louis A. Lehr,
    Jr., Premises Liability 3d § 54:41 (2012) (“Wilful conduct as an exception
    to statutory recreational use tort immunity consists of intentional acts of
    an unreasonable character performed in disregard of a known or obvious
    risk so great as to make it highly probable that harm will result.”).16
    Additionally, the phrase “willful or malicious” as used in section
    461C.6 ought be interpreted in tandem with the phrase “willful and
    wanton,” as used in the punitive damage statute.                 See Iowa Code
    § 668A.1(1)(a). The latter standard means
    “[t]he actor has intentionally done an act of unreasonable
    character in disregard of a known or obvious risk that was
    so great as to make it highly probable that harm would
    follow, and which thus is usually accompanied by a
    conscious indifference to the consequences.”
    16Here,Iowa’s exception for a “willful or malicious failure to guard or warn”
    corresponds to that in the model act. Compare Iowa Code § 461C.6, with Council of
    State Governments, 24 Suggested State Legislation at 151.
    69
    Brokaw v. Winfield-Mt. Union Cmty. Sch. Dist., 
    788 N.W.2d 386
    , 396 (Iowa
    2010) (quoting McClure v. Walgreen Co., 
    613 N.W.2d 225
    , 230 (Iowa
    2000)). That threshold has not been met here.
    V. Is There a “Tour Guide” Exception?
    Finally, Sallee argues that by guiding the group around the farm,
    including      into   the   hayloft,   the    Stewarts     performed    a   voluntary
    undertaking within the meaning of Restatement (Second) of Torts section
    323 that is not covered by the recreational use immunity.17 The district
    court rejected this argument.           In her opening brief on appeal, Sallee
    renewed her section 323 argument. In her reply brief, she recast this
    argument into one based on section 7 of the Restatement (Third) of Torts.
    In that form, the court of appeals accepted it and on that basis reversed
    the district court’s grant of summary judgment.                    Regardless of the
    Restatement box into which this argument falls, I do not believe there is
    a “tour guide” exception to the recreational use immunity in this case.18
    17Restatement   (Second) of Torts section 323 (1965) provides:
    One who undertakes, gratuitously or for consideration, to render services
    to another which he should recognize as necessary for the protection of
    the other’s person or things, is subject to liability to the other for
    physical harm resulting from his failure to exercise reasonable care to
    perform his undertaking, if
    (a) his failure to exercise such care increases the risk of such
    harm, or
    (b) the harm is suffered because of the other’s reliance upon the
    undertaking.
    18The   majority does not reach this issue. The special concurrence does, stating
    that Sallee in effect brought a “negligent supervision” claim. This is simply wrong. A
    negligent supervision claim arises when an employer negligently supervises an
    employee, whose tortious or wrongful act then harms the plaintiff. See Am. Family Mut.
    Ins. Co. v. Corrigan, 
    697 N.W.2d 108
    , 112 (Iowa 2005) (noting that negligent supervision
    includes as an element an underlying tort or wrongful act committed by the person who
    was not properly supervised); Estate of Harris v. Papa John’s Pizza, 
    679 N.W.2d 673
    ,
    680 (Iowa 2004) (listing the elements of negligent supervision). Sallee does not allege
    that the Stewarts negligently supervised an employee whose tortious or wrongful act
    harmed her. Regardless, the proper focus should be on the language of sections 461C.3
    and 461C.4(1) and whether they bar Sallee’s claim, whatever nomenclature is used.
    70
    In Scott v. Wright, we found that the recreational use immunity did
    not bar a claim against the defendants based on the negligent driving of
    a tractor on their property. 
    486 N.W.2d 40
    , 42–43 (Iowa 1992). In that
    case, the plaintiff was seriously injured when she fell off a hay wagon
    that was being pulled by a tractor owned by the defendants and operated
    by their son-in-law. Scott, 486 N.W.2d at 41. In affirming a jury verdict
    in favor of the plaintiff, we reasoned that
    Scott’s suit against Wrights rests—not on duties addressed
    by section 111C.3 [now section 461C.3]—but on vicarious
    liability for alleged negligence in the operation of a motor
    vehicle. We are convinced, as was the district court, that
    this intervening act of negligence takes the case outside the
    purview of chapter 111C.
    By its terms, section 111C.3 immunizes landowners
    from only two specific duties of care toward persons using
    agricultural property for recreational purposes: to keep the
    premises safe and to warn of dangerous conditions. Nothing
    in the language of chapter 111C suggests a legislative intent
    to immunize all negligent acts of landowners, their agents, or
    employees. Nor do we believe such broad application of the
    statute would serve the public purpose envisioned by the
    legislature. Though focused on reducing landowner liability,
    the statute was also enacted to serve “a growing need for
    additional recreation areas for use by our citizenry.”
    Explanation to H.F. 151 at 3, 62nd G.A. (Iowa 1967). The
    public’s incentive to enter and enjoy private agricultural land
    would be greatly diminished if users were subject, without
    recourse, to human error as well as natural hazards.
    Because the language of chapter 111C is couched in
    terms of premises liability, and the legislative history of the
    statute evinces no other motive for its passage, we are
    convinced the court correctly refused to apply it in this case.
    Id. at 42.
    Sallee contends that Scott stands for the proposition that she can
    sue over any “affirmative act” of negligence by the landowner. She also
    urges that Scott allows a party to sue when the claim is for “human
    error” as opposed to “natural hazards.” See id. I do not read Scott so
    71
    broadly.19 Scott emphasized that the claim was not for premises liability,
    and therefore, it was not foreclosed by the statute. Id. Scott’s focus on
    the statutory language was appropriate. The statute makes clear that
    except as provided in section 461C.6, a landowner “owes no duty of care
    to keep the premises safe for entry or use by others for recreational
    purposes . . . or to give any warning of a dangerous condition, use,
    structure, or activity on such premises to persons entering for such
    purposes.” Iowa Code § 461C.3 (emphasis added). This language does
    not distinguish among duties derived from different sections of the
    Restatement or distinguish between active and passive negligence. So
    long as the plaintiff’s contention is that the landowner failed to keep the
    premises safe for entry or use, or failed to warn of a dangerous condition
    or structure, the action is barred if the other requirements of chapter
    461C have been met and if section 461C.6 does not apply. Scott’s claim
    went forward because she was asserting negligent driving, not a failure to
    keep premises safe for entry or use or a failure to warn about a
    dangerous condition or structure.
    Sallee’s claim, however, has to do with the condition of the
    premises. She alleges either that (1) the hayloft was not safe, (2) Stewart
    should have warned her about it, or (3) Stewart should not have
    encouraged the group to go there. See Reply Brief for Appellant at 16
    (“This required the Stewarts to exercise reasonable care, either to take
    precautions to fix dangers like the hole or not take them into dangerous
    areas or to warn them of any dangers like the hole.”). The first two of
    these claims fall squarely within section 461C.3. I believe the third does
    as well. If a landowner “owes no duty of care to keep the premises safe
    19Obviously,  Bird involved a case of alleged human error—stretching a cable
    across an access road and not warning about it. See 498 N.W.2d at 408.
    72
    for entry or use by others for recreational purposes,” see Iowa Code
    § 461C.3, it follows that the landowner does not breach a duty when he
    leads a group into an area whose safety he has no duty to maintain.
    This conclusion is reinforced by section 461C.4, which specifically
    provides that a holder of land “who either directly or indirectly invites or
    permits without charge any person to use such property for recreational
    purposes or urban deer control does not thereby . . . [e]xtend any
    assurance that the premises are safe for any purpose.”                  Iowa Code
    § 461C.4(1).    The essence of Sallee’s third theory is that by allegedly
    inviting her into the hayloft, Matthew Stewart implicitly assured her that
    it was safe for her use.
    In Klepper v. City of Milford, the plaintiff tried unsuccessfully to
    rely on Restatement (Second) of Torts section 323 as an exception to the
    recreational use immunity. 
    825 F.2d 1440
    , 1448–50 (10th Cir. 1987).20
    That case involved a serviceman on weekend leave who was paralyzed
    after diving head first from a moored boat into murky but shallow water.
    Klepper, 825 F.2d at 1441–42.            There was a sign warning against
    swimming but whether it was actually in place or had been dislodged
    was subject to dispute. Id. at 1442. Invoking section 323, the plaintiff
    argued the defendants had assumed a duty when they “undertook to
    erect a warning sign near the boat dock” and “undertook to make
    quarterly inspections.”      Id. at 1448–49.       The United States Court of
    Appeals for the Tenth Circuit rejected the argument that such an
    “assumed duty” negated the statutory recreational use immunity,
    explaining as follows:
    20Once   again, this is an area where Iowa has adopted the model act language.
    Compare Iowa Code § 461C.3, with Council of State Governments, 24 Suggested State
    Legislation at 151.
    73
    We agree with the district court that there is no
    compulsion under Kansas law to extend sections 323 and
    324A of the Restatement to the RUS [statutory recreational
    use immunity] context.         The RUS itself is a statutory
    modification of the common law of torts and provides for no
    liability for simple negligence.       Instead, it provides for
    liability only where conduct is willful or malicious or where
    consideration is given in return for use of the recreational
    facilities. If the Kansas legislature had wanted to provide for
    additional exceptions, such as liability for negligent
    inspections, it could have so stated. To rule otherwise would
    have the effect of defeating the purpose of the RUS. As the
    United States points out, “If a negligent, gratuitous
    inspection results in liability, the requirement in the RUS for
    the higher standard for liability, i.e., willfulness or
    maliciousness, has been eliminated.”
    Id. at 1450. The Tenth Circuit’s reading of the statute is logical, and the
    same logic should apply here. Our general assembly, like the Kansas
    legislature, provided that (subject to certain exceptions) landowners
    would have no duty “to keep the premises safe for entry or use by others
    for recreational purposes,” or “to give any warning of a dangerous
    condition, use, structure, or activity on such premises to persons
    entering for such purposes.” Iowa Code § 461C; Kan. Stat. Ann. § 58–
    3203 (2005). Whether the duty is “assumed” or “preexisting” does not
    factor into the analysis so long as the claimed breach of duty is
    precluded from being raised by the statute.
    In Palmer, the United States Court of Appeals for the Ninth Circuit
    engaged in a similar analysis in overruling an argument based on the
    undertaking theory articulated in Restatement (Second) of Torts section
    323. See 945 F.2d at 1137–38. The plaintiff, who slipped and fell while
    descending a flight of stairs at a swimming pool, urged that the
    defendant voluntarily undertook a duty of reasonable care “by hiring
    lifeguards, washing down the steps, and generally maintaining the pool
    area.” Id. at 1137. The Ninth Circuit rejected this argument:
    74
    Application of the HRUS [Hawaii recreational use immunity
    statute] precludes other theories of liability based upon mere
    negligence. Nothing in the language of the statute or its
    legislative history indicates that Hawaii intended the HRUS
    to apply only when the landowner fails to take any
    precautionary measures to ensure the safety of recreational
    users.
    Id.; see also Ervin v. City of Kenosha, 
    464 N.W.2d 654
    , 657–660 (Wis.
    1991) (rejecting the plaintiffs’ claim that the negligence of lifeguards took
    the case outside the recreational use immunity based on a theory of
    “active negligence” or “gratuitous acts” and noting that if liability were
    imposed based on such a theory, “these facilities may not be provided”).21
    VI. Conclusion.
    To sum up: Iowa’s recreational use law has always covered
    agricultural lands and appurtenant buildings, such as a barn. Jumping
    in hay is a sport in the same sense that other activities listed in section
    461C.2(5) are sports, and in the same sense that the term was used in
    City of Marion. See 643 N.W.2d at 206–08. Jumping in hay is also an
    activity frequently engaged in outdoors.                    Although Sallee was not
    21Sena  v. Town of Greenfield is not on point because New York has a special rule
    for supervised municipal parks. See 
    696 N.E.2d 996
    , 999 (N.Y. 1998).
    Sallee also argues that she has a claim against the Stewarts under Restatement
    (Second) of Torts section 310 (1965) (“Conscious Misrepresentation Involving Risk of
    Physical Harm”). That section provides:
    An actor who makes a misrepresentation is subject to liability to another
    for physical harm which results from an act done by the other or a third
    person in reliance upon the truth of the representation, if the actor
    (a) intends his statement to induce or should realize that it is
    likely to induce action by the other, or a third person, which involves an
    unreasonable risk of physical harm to the other, and
    (b) knows
    (i) that the statement is false, or
    (ii) that he has not the knowledge which he professes.
    I agree with the Stewarts that Sallee has not shown an affirmative misrepresentation.
    Accordingly, I would not reach the question whether chapter 461C would bar such a
    claim in any event.
    75
    jumping in the hay herself, she was there as a chaperone to serve the
    overall recreational purpose.     Finally, this is a premises liability case
    where the alleged duty sought to be imposed is foreclosed by sections
    461C.3 and 461C.4(1).
    Notwithstanding its extensive citations to historical materials, law
    review articles, and other states’ laws, I think the majority opinion
    misses the essential point: Our recreational use law protects farmers
    who want to open up their farm properties so others can play there for
    free. At least it did so until today.
    I respectfully dissent and would affirm the judgment of the district
    court in its entirety.
    Waterman, J., joins this dissent.
