(plaintiffs sought rezoning of property from agricultural to commercial to allow operation of seasonal deer processing facility and retail counter; agreement reached restricting use of tract to wild game processing and associated activities in addition to allowing a single family residence; defendant approved zoning request consistent with agreement; plaintiffs again sought rezoning to add service of ready to eat food; request denied; retail services could be conducted year-round, but plaintiffs could not serve ready-to-eat foods or have a deli shop; on appeal, court determined that ordinance limited plaintiffs’ retail services to seasonal operations between October and January; deli-style sandwiches not permitted; retail service does not comprise ready-to-eat products).
