On three days' worth of food, remember those stranded after Katrina were there longer than three days. Most people evacuated for Ike, but I'll be interested in how long it takes to get power, water, and gas back on around Galveston.

I live in the San Francisco Bay Area, and we won't have warning to evacuate. My worst case scenario is that here on the Peninsula, all the roads will be cut by falling overpasses and evacuation will not be possible. There are always fires after earthquakes, so it's possible devastation in my area will be similar to Katrina's effects on New Orleans. Three days of food won't be enough for us to live on till FEMA can get in here with any relief, if worse comes to worse.

Your mileage will vary, of course, but I'd ask you if three days is really enough in your circumstances, geographically and disaster-wise.
