One of the great things about a canoe trip down a river is I can take along a full size lawn chair with armrests. Not only is it comfortable, but it's easy for me to get in and out of.
I wish I could take a lawn chair on backpacks, but I can't There are backpacking chairs as light as a pound, but they are low to the ground and don't have arms. If you are young, have good knees and short legs, they probably work great. Not so much if you are 65, have less than perfect knees and buy pants with a 34-36 inch inseam.
Sitting on a log just doesn't cut it. Neither does retiring to my tent, while there is still daylight, because my back needs a rest. There probably isn't a perfect solution, but I'm going to give hammocks another try. About a thousand years ago, when I first started backpacking, I used to take a cheap net hammock on overnight trips. I remember it being pretty comfy, but there must have been a reason I stopped taking it along. Can't really remember. In any event, the new ones are most likely better and easier to set up.
So, I've ordered a hammock and straps and, even, a mosquito net made for it. I'm not sure how much of that I'll be willing to carry. Don't really need straps. Dacron rope and a trucker's hitch should work fine. Supposedly the straps are easier on trees. I might try sleeping in it, if it looks like there is little chance of rain.
If and when I use it, I'll give an update.
