Three years ago I lost a leg and thought my hiking and backpacking days were over. Wrong! With the new prosthetic devises they have now I'm back to roaming the trails and enjoying mother nature again. Like RamblinRev says, "I'm slow and gimpy", but I'm still out there.
The biggest problem I have (had) is getting in and out of a tent. I can usually find a spot where I can sit, but a spot where I can sit that is convienient to a good tent spot isn't easy. Taking the leg off isn't much of a problem, but I really need to be in a sitting position to get it back on. I have to stand to get it to seat right, and this is a hassle when you have to sit on the ground or inside a tent. And getting up from the ground isn't always easy (or pretty) on one leg.
So after finding info on hammocking here and at other sites, and with some great help from Mule (he spent a couple of hours showing me some hammocks and letting me try some out - then sold me one of his). I have left the dark world of ground dwellers and come into the light. I are now a "hanger".
Other than the obvious, a great nights sleep, with a hammock I always have a place to sit and it's always convienent to my bed. This allows me to take my leg off at night and get it back on in the morning without having to crawl twenty feet to the tent or a seat. I can cook from there and just relax if I want. I can put up the hammock and tarp without having to bend over or squat down (except for stakes, and one or two are a lot better than four or six). I don't have to crawl in and out of it with wet rain gear. And I can dress and undress standing up. I still have a couple of issues to work out, like what to do with my leg at night. I'm not sure I want to leave it on the ground and wake up one morning to find that some critter has wondered off with it (not a pretty sight to see a one legged old man crawling through the bushes looking for his leg - maybe funny, but not pretty).
So, IMHO anyone with leg or back dissabilities can definately benefit from a hammock. Besides, where else can you get a better nights sleep in the wilderness?
I'm so out of shape ......I passed gas yesterday and pulled a muscle!
