For most of us, an elaborate doomsday bunker is overkill. But, when facing down a tornado, hurricane, blizzard, or whatever Mother Nature flings at you, a little preparation can save you from a real-life version of the grocery store frenzy in an end time zombie flick. Start with basics, like a three-day supply of water (ready.gov recommends one gallon per person per day), batteries, and the infinitely versatile duct tape. Then store these other essentials in a waterproof bucket. There—no fighting over Manwich.
