That is pretty cool. I know when I went hiking in the mountains I pack a Hennessey hammock but if you use the rain fly you can't see anything above or more then 2 or 3 feet off the sides of you. I bet you could rent this little camping cabins out to people all day long. Sure beats sleeping in a tent on the ground especially in cold or wet weather. I am surprised that people had stress reduction sleeping in those since sleeping in the woods has an unsafe feeling for a lot of the modernized world now a days. Love the concept though thank you for the article.
