Oi, I haven't been out there in months, actually. It stayed pretty dry, and I was able to sleep comfortably in it for awhile. But without funds or enough blankets around, I didn't have anything to insulate it with for the winter. Nearly froze my ass off out there one night after the weather changed, even with a fire going. Tarps might keep rain out, but they don't keep the heat in well. I might try to scavenge felt from old car trunks, maybe start piling up debris around it as well. I think I have to clean it out first, whatever I do, since I left a bunch of stuff in there.
