camping on TN public lands illegal and a felony???

In a related topic, I just recently read that that a federal apellate court is going to hear a case banning local municipalities from forbidding overnight parking on commercial property when the property owner allows it, such as Walmart etc, on that such a ban infringes on the property owner's first amendment rights. I don't recall where I read it, but it would have been a reliable news source.

Anyone else?
