I've seen some plastic bags of beef jerky, rather salty but not requiring refrigeration.

Here in northern Alabama, we had a 4.5 day power outage from a tornado last year. It seems we get all our power from one group of power plants, and the tornado hit the area where the several high-voltage power lines that bring us power were spreading out from that group of power plants.

To those planning to use microwaves: I've never seen a microwave that didn't require electricity, so those of you might need to look for the gasoline-powered generators that can give your home some electricity, although probably less than usual.
