A tractor rumbles along the rolling hills of Green Meadows Petting Farm's back 40 as it pulls hayride passengers toward the farm’s animals' barns and pens. There, hands of all ages can snuggle on the fuzzy fleece of a baby goat brush against the bristly hide of the 600-pound Petunia the Pig, or comb fingers into the soft mane of Precious the Pony. Farmers on the staff also share insights and anecdotes on the farm and its four-legged friends as guests roam the farm at their leisure. For the Keyes family, of all the sights and sounds on a farm that's been in the family since 1964, the ones they enjoy most watching and hearing are from the children and parents who come to visit.
