I really love National Parks, and I am planning to hit up Yosemite and a couple others out west this summer. Well I got this idea that I could just camp in the parks while I was there, maybe just off some of the hiking trails they have through the park. Anyone have any experience doing this? I know there are supposed to be designated spots blah blah blah, but I don't see a problem as long as I'm far enough away that a Park Ranger doesn't spot me. Thoughts?
