Meh, I'll just keep worrying about drought, tornadoes, hurricanes etc...the regular stuff. Oh, and running out of oil. Which will happen sooner? Only time will tell.
I'm from Miami, and we had lots of emergency supplies on hand...flashlights, batteries, water etc. Nothing was ever so bad that we couldn't just drive to the grocery store (or Walmart) and none of these things helped much when our house flooded, twice, and got broken into. Those were the real disasters we faced. I live so inland now, I don't bother keeping anything on hand except water and paper plates/utensils in case the septic fails.
