Those are some really cool trails. Now I want a bike again. Sadly not for a while though.
No idea what PA is like, but in NY they threw a bit of a fit about Grandpa driving his Saturn out to pick blackberries. Considering they had foot deep ruts in places from the log skidder and log trucks where they had clearcut half the hill I really don't see what he was hurting, but sometimes governments are funny like that. OTOH He did drive by the "No motorized vehicles" sign, which should have given him a hint that they didn't want him driving there.
I went to the doctor the other day, he asked how much coffee I usually drink in a day. I told him "Oh, forty cups or so". Surprised he asked "Doesn't that keep you awake?" I replied "It helps".
