I'm planning a backpacking trip for this summer. I'm trying to get more info on the Smokeys. I realize that certain campsites require a reservation, and other back country campsites are simply first come first serve.

My goal: minimize contact with other people. I'm not going into the wilderness to share a shelter with 20 others.

I understand that you're supposed to stay in the shelters if there's room. In other words: no tents unless the shelters are full. What about hammocks? Do the designated shelters and campsites have adequate hanging opportunities?
