How have I missed this thread!?
My concern is being able to find free camp sites along the way. Any advice for this???
Free campsites are everywhere, man. They're called powerlines. Try to get at least an hour out of a major city, get off the interstate onto a side road, and look for powerlines, radio towers, or even big sections of woods. Always get about 100 feet back in the woods, keep your lights/engine off and keep quiet. Youll hear them coming long before anybody can get on top of you.
I've crossed the continent several times doing that. Heck, I slept in the woods across the street from YOUR local police station in Bowling Green once. Even had a fire. I've gotten less and less picky about where I sleep on road trips. I did it for a whole semester so I wouldn't have to pay rent last year.
No, I'm not homeless....Ive got a tent!
