I don't know about the states but up here in the frosty north we have lot's of forested land, even whithin alot of our cities. I see where people have made campsites on them. Government land is called crown land here,and there is alot of crown land in these here parts, so it is very easy to find a spot to camp. The one problem is wildlife, even though this is the capitol we have had moose wander into the industrial sections of the city. In the greenbelt there are countless numbers of places. Everything is so spread out round here that unless you are right near the heart of the city there is no problem camping out. I once slept in a ditch on the side of the highway when I was hitch hiking and could not get a ride. Check out Indoplanetyanin's touring journal, he finds some really nice places to free camp and does not seem to get in any trouble doing it. One can learn alot from his journal.
