I don't know of anything that far south in VA, but you're right over the border from the Carolina boys and they may be able to give you ideas. Tasker's Gap in the George Washington National Forest is near Edinburg, VA and may be on your way home, and if you're coming up I 81 you're only a few miles from my house- stop in and look at all the old junk!
Stuck in the seventies- not in the swamp.
