The other day someone said some "park rangers" and such get upset about hanging because it damages the trees. I plan to hang in many different places but I've been going to the smokey mtns my whole life. My question is do they restrict you from hanging say in "Elkmont"? As many times as I've been there I don't think I've ever seen a hammock. Only tents and rv's. Also what about state parks in TN and Ms. Mainly I'm talking about campgrounds that you would pull an rv too.
