When I started toying, and later loving the idea of using a hammock, I had never seen one while out backpacking. So I start using them and my buddies, who stuck there noses up before, start to try them. Next thing you know there are 5 out of 8 of us in hammocks. Then I start seeing more and more when I am out for a trek. I was out this past weekend in the Smokies and I swear I saw more hammocks than tents, and we were in some fairly popular spots.
One down side, it is getting harder to find good trees lol. I found myself saying, "This would be easier if I had a tent." but then slept like a baby and soon forgot that thought.
Another down side is the number of requests from friends to make/show them how to make a tarp, an UQ, a TQ and more and more. When will I have time to make myself another lol.
