Well I had the good fortune the other day of an incredible deal on some USGI shelter halves. I got 3 halves, two poles, and 10 stakes for a price I still can't believe. Nonetheless these will be a great addition to the fall and winter seasons. The other day I got them out in the backyard to play around with them a little.
First configuration is the pup tent. (My daughter thought this was very fun to setup and play in)
Next up is with just one half. I've heard this setup is very nice when it's very cold as you set it up facing the fire so the heat reflects back on you. You have even setup a reflector blanket or space blanket on the inside wall to aid in the heat reflection. I'll give it a try this winter and and we'll see how it does.
