I would guess that around here, our most likely disaster would be a flood. We're very close to the Ohio River, and a large creek that feeds into it runs across the street. Luckily, we're up on a hill, so it would take a flood of Noah's proportions to get to our house, but we could easily be stranded here.
I do remember being in high school, doing earthquake drills where we crouched under those flimsy school desks (so if something fell on you, you would get smashed by it AND the desk!). I think that if the New Madrid fault goes, we could be fairly hard hit by it.
Anyway, we are building our store of food. DH bought these 'emergency food kits' with 2 weeks of freeze dried crap in it, but I'd rather eat real food as long as possible. When we empty a milk carton, I rinse them out & refill them with water, and stow that away. We don't have enough to make too much of a difference, but every little bit helps. We definitely need a non-electric heating source. The farm store out here has got a bunch of wood stoves on sale, so I'm trying to get DH to go out & look at them. So we still have a ways to go, but I'd put money on our being more prepared than ANYbody we know.
And we do have cash stowed away at the house, too.
