Built this today. It was pretty cozy with a canvas tarp thrown over it. Took about four hours. Be interesting to see how many years it lasts, and which part fails first. Indians around here used to make shelters like these and use them seasonally, leaving the frames in place and taking the bark or skin roofing materials with them when they moved from the mountains to the seacoast and back. They also made raised beds by planting forked sticks in the ground. I think I'll add one of those and use it this deer season.
