Great suggestions. Also, another pair of boots, and a small camp axe, or hatchet, for cutting firewood, fallen trees across the road, for chipping ice, around the vehicles' tires, or for water. And a small pot to boil water, and tea bags. Also six or eight of those little hotties, hand warmers. Ooh, just remembered, "Toilet paper"!! For me I always have fire arm handy.
