What's really funny is how damn oblivious the lot of you are to these chaps, not the stupid jokes you made about their parents. Funny what happens when you actually KNOW a person, rather then argue with them over the inter-verse, congrats, you have put time into being intentionally unhelpful.
Anyway, back on subject. Wish I could help you guys out. I don't know of any legal free campsites anywhere, at all. And you are probably way past the areas I know now. But there is a lot of land out by the Byron area, Marsh Creek road all that jazz that isn't heavily monitored by cops. I used to live out there and play with the cows in the middle of no where at 3 in the morning, you can get away with it, and on foot, no pig is going to bother catching you, they sure as hell aren't going to drive over those vehicle death traps. However I would stay away from trying to squat places like Concord, lived there too it's pretty upper class and I don't think you would have any luck finding a squat around there, or even an inhabitable abandoned building to crash in. Any farther north I know nothing of, been to San Fran a few times, believe it or not you can get away with murder there, or maybe I'm just that lucky. But I still don't know shit about the area and what's too risky and what isn't, but the homeless lads seem to do alright, though they don't seem to ever stop moving.
