Nice Cave/Igloo. Who sleeps in it? Last Winter a friend and I decided we wanted to sleep in a snow cave. We went out to a field and had to dig up a huge pile by ourselves, and then we dug the cave out of that. Was awesome
Me and my boys slept in it. It's an actual igloo made from bricks of snow, not a hollowed out cave in a pile. I built a snow brick mold, and we made the bricks, and stacked them up like that.
I have another tip, whenever I sleep out in cold like that I always have a pair of extra thick wool, loose fitting socks for sleeping in the sleeping bag. That way I always have perfectly dry feet in bed. (dry=warm)
