As a youngster, there was nothing I liked better than Sunday afternoons at my grandfather's farm in western Pennsylvania. Surrounded by miles of winding stone walls, the house and field provided endless hours of fun for a city kid like me. I was used to tidy living rooms that seemed to whisper, "Not to be touched!"
