[Night Hides Not]

We keep a sleeping bag and a bag of dry food, matches, gloves, a thermal blanket, first-aid kit, and a couple gallons of water.

Here's another item you might want to add: one of those new (portable) jump start units. I got one for Christmas, and it includes a worklight, DC converter, and air compressor. It will come in handy, as I'm the one driving around in an older vehicle.

I was just thinking that a small hatchet, a tarp, bundle of parachute cord, and some flares might also be good to include in an emergency kit. Hatchet to cut firewood if the gas in the car runs out, tarp and parachute cord to make a temporary shelter if need be, and flares to help signal searchers on the ground and in the air.
