Won't forget -52' at Ft. Drum, in a snow cave!
Don't sleep with your clothes on in a sleeping bag or under covers! I did, but just once, went outside and ice formed on my clothes under my parka! It takes forever to dry out. Roll up your clothes and put them in the bag by your feet, you won't sweat on them and put them on in the bag before you get out.
Even a couple candles will help heat a small space, several under an ammo can with rocks in it and the lid partly opened makes a difference, but don't touch it in the morning, it can burn you. You can also use a can, like a hobo stove.
Wool socks rule
, change them if they get damp. Boots (shoes) can also go in a plastic bag (because they are dirty) and then go in the sleeping bag, leave them outside and you may have cold wet frost in them and on them.
Do not touch metal objects in sub-zero stuff, like a kid putting his tounge on a door knob...
Sunglasses on outside. Keep lip chap stuff handy and use it on the face as well as the lips, exposed skin chaps, cracks and it hurts, wind
burn as well for you fast boaters...LOL
I had a mustashe and got a drink at a water
fountain in a building, but my parka on and stepped outside, in seconds the hair broke because I still had water on it...I shaved it off. Otherwise skip shaving if skin is to be exposed right after running a razor over it, it burns.
I think I'd keep a small V berth closed off from the main cabin
using it as my warm spot, little cooler in the cabin.
Now, I have a question....does anyone use computer fans to keep air circulating in a cabin, they draw very little and come in various sizes. So if a vent were craked with a fan in the fabricated as an exhaust
vent seems it would move just enough air to vent without sucking your heat out????
