Tucked into the rolling hills of Stone Valley, Cole Farm seems like a typical central Pennsylvania farm. A gravel driveway slopes down to a steel and wood-plank bridge that spans Shaver’s Creek. The path continues relatively flat, past a murky green retention pond and two barns, to a log farmhouse nestled at the base of a hill. A spring trickles through the wooded swale west of the house. Sloping fields are flush with alfalfa, corn, hay grass, and wheat.
