Hurricane Isabel, which was downgraded to a tropical storm by the time it passed over us, left us without water for five days and without power for seven days. Luckily, we have a gas stove, gas grill and gas water heater, so we could cook and take showers. I felt really anxious during that time, so it was a huge comfort to have a battery-powered TV and, at the time, a device (can't remember what it was now - an iPod?) that could receive radio signals, and the radio stations cooperated with the TV stations to broadcast the news that way, so people would know where they could get ice, etc.
I filled our bathtub in the downstairs bathroom before the storm. Hubby laughed at me, but as I said, we had no water for five days - the pumping station around the corner was flooded, so they shut it down. With the tub water and a bucket, though, we could flush the toilet.
And since then, I've been prescribed a medication that has to be refrigerated, so we bought a generator and got a tax deduction for it.
I've been complacent this year. I'm feeling like I should get some supplies, just in case.
