I haven't seen the movie but I do have some emergency stuff stashed. I have been laughed at about having extra water, etc. on hand. When the power grid went down a few years ago, I had light (oil lamp), I had iced tea (extra ice in freezer was put into smaller cooler for use in keeping milk fresh and iced drinks), I had coffee in the morning (gas stove and camping coffee pot). I could even flush my toilet with water from the rain barrels. I don't get laughed at as much since then.
