First let me say I'm still a total newb. I have 2 nights in a hammock.
I have a back injury that, while managed pretty well right now, has the potential to cause an awful lot of discomfort. I did a lot of hiking and camping prior to the injury 5 years ago, but only in the last year have I recuperated to the point where I can get back in the woods. Sleeping on the ground still causes issues though.
I was reading AWOL On The Appalachian Trail around Thanksgiving this year, and there was a very brief mention of someone hiking the trail using a hammock. It was interesting, but I can't really sleep on my back, so I didn't put a lot of thought into it. Then just on a whim I googled 'side sleeping in a hammock', and this forum popped up, along with Shug's videos.
I'm an engineer, and love homebrewing anything and everything I can. I'm a ham radio operator and build a lot of my own equipment for that, so hammock camping is just a perfect fit all around.
