Well, sleeping under a tarp was the 'gateway drug' for me.
I loved the tarp, but I was not happy with any kind of sleeping pad I had.
Getting up off the ground after a long day and a long night tossing and turning was a pain.
I think I found Sgt. Rock's site first, while looking for tarp info, then Just Jeff's, then this forum. Lurked around and decided to try a cheapie hammock from amazon.
