Interesting question. Personally, I am not trying to get worried about it. The way I see it, if I'm not actually hit, then the gov. should provide what I will need. As for water, you don't need to stock up on it. If there is a disaster, run a bath. Drop 1/8 cup bleach into the tub. Let sit 24 hours. The bleach will kill any bacteria in the water, and by letting it sit for a day, all the sediment will sink to the bottom. Scary what you can learn in Maxim magazine
