I wish somebody would invent a hammock/tent. It would have a tough enough bottom to be used on the ground, with some kind of edge strapping to keep the edges slightly above, etc. It would require two poles, but that could be the next invention. A tough hiking staff, pointed at both ends, that separates in the middle to be used to pitch the hammock/tent on the ground when there are no trees around. I wish! I wonder if anybody else has given any thought to how to make this kind of idea work very well. It might require an small adapter-piece, like a metal guitar slide or something, that fits around the screw piece of the staff, to avoid damaging them when hammering. I can't imagine it would be too hard, and I know I would buy one, I mean two!
