I wish you would have said something sooner, I would need some serious negotiating with management ( the wife ) to get out this weekend.
Last year I did a two nighter on these trails. Lots of good water spots and not quite as crowded as SNP on the weekend. I camped at campsites near Big Scloss and the Gerhart Shelter. But I was on the ground. You could set up a hammock anywhere. Here are some links to where I got most of my info. If you are interested I could send you some of my maps that I made for the trip. You could also just look around on the site the links are on. It is pretty nice.
