No, having a fire in our kind of winter *is* mandatory. Ok, admittedly I've "cold camped" with only a stove overnight in Jasper park where I am not allowed to have one. but that basically then consists of hiding in a sleeping bag for 15 hours. - enough to make me go somewhere I can burn something. -25C and 6 hours of daylight does not make life pleasant without a fire. I need my warmth and "caveman TV" at a minimum
