I'm 46 now and have had a sore back the last few times I went camping. I'm looking at hammocks as an alternative. I've used hammocks in the backyard durring the day for naps but never all night. I'm hoping to change that soon. I have 3 boys under 8 and they do everything I do, so I actually think my first step will be to make them some hammocks, so that when I make or buy mine I can keep them off of it. I'm trying to set us all up with something on the cheap and will likely start with sleeping bags and pads.
