As a resident of the eastern part of the infamous "Tornado Alley", we're set for most natural disasters, Spring, Summer or Winter. Watched two twisters bounce by last year. We're accomplished primitive campers, and I'm somewhat of a self-sufficient type, so we're in fairly good shape without utilities.
But, I also live less than 50 miles (downwind) from one of the largest VX nerve gas depositories in the world. Luckily, the security there is beyond tight, so I'm not very concerned. I'm not sure what I could do about that anyways, besides run far away if I get word soon enough.
