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 or sheep, brush against the bristly hide of the 700-pound Patty the Pig, or comb fingers into the soft mane of Lad 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 Charlie and Mavis Keyes, 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. It's a thrill, Charlie says, to hear the kids say that they had "the best day ever," providing a happy counterpoint to childhood days that include trips to the doctor's and punishments to file and catalogue a sister's dolls' dresses.
