>>666494National Parks are free to camp, areas off the beaten path (i.e fields and wooded areas away from public eyes), simply asking someone who has a large portion of land. Ive asked a couple of times if I may put a small tent on the edge of there property and have never been told no. On the big cross country trip im gonna try to make it from national forest to national forest as its free to camp anywhere in them. Couch surfers good every once in a while. Truck stations and camp sites offer showers and most couch surfer hosts will let you shower.
