Quinn Werner’s backyard pumpkin patch overlooks a wooded creek. In the winter, when the maples and oaks stand like toothpicks and snow coats the western Pennsylvania valley, Werner gazes out his kitchen window and caresses his prizewinning seeds. The topsoil is frozen solid and his orange Kubota tractor gleams in the garage like a showroom floor model. He is not a big talker, but every Thursday his buddy Dave Stelts phones, and their conversation always comes back to springtime, to the patch and the weigh-off.
