You make a great argument for the emergency blanket shelter. Yeah, I haven't really seen or heard about anyone trying something like that. On some of those survival shows I guess but not even close to the extent you're talking about. You may really be onto something. I'm tempted to get to work on one myself. I hear what you're saying about the downpour. After studying over your structure the main question I had about it is whether or not or could stand up in harsh conditions. But it sounds like you're on your way to solving that "problem". Way cool, man. I appreciate you taking the time to lay it out for me.
