I live in Ohio and not much really happens around here, except for the occasional tornado warning, which rarely ever produces anything significant. That's really the biggest disaster I can think of happening in these parts, so I don't have a large fear of ever having to evacuate (unless the house catches fire or we have a gas leak, in which case we're probably not going to have any time to grab extra items anyway) so I guess you could say I'm only 'minimally' prepared. I've got extra food stored, a couple sheets of bottled water, a couple of food kits with the 25-year shelf life edibles, flashlights, matches, batteries and transistor radios, a camp stove, a manual can opener, plenty of blankets if we lose power during a winter storm, that sort of thing. I even have 2 large packages of adult body wipes to keep clean in the event we have no water.
If some weird disaster were to hit that would force my son and I to stay homebound for several days to a week or longer, we've got enough to survive on for that length of time.
