I'm assuming we would be comfortable and B.S.ing would certainly pass the night quicker than huddling in a shelter trying to sleep/pass the night. And B.S.ing is what we do best. If it were a blizzard or extremely cold, I would certainly break out the shelter building equipment which would be with me, just wondering about sleep, if cold? Which was answered, and hadn't thought about the sleeping pad which would be bulky, had assumed a lot of pine boughs would suffice, will consider the inflatable therma rest type pad, but the seat off of my sled would keep my aa...butt warm. Snow mobiler's generally carry a wood saw, for unexpected tree parking jobs. So fire wood would be plentiful... And collecting it would be a warming episode, and pass some time as well.
