I'm in an enviable position weather-wise. I've lived in the San Francisco Bay Area since 1992, and it's never been below freezing and I've never lived in an air-conditioned house here.
Because I expect an earthquake, I've got a month's worth of canned and packaged food (for us two), a big propane tank (well, big to me), a propane grill, two propane camp stoves, a dual-fuel (white gas/unleaded gas) camp stove, and enough water to get me started filtering the stream that runs through the park across the street.
We've got survival candles, romantic candles, battery powered lanterns, a couple of 100 Amp-hour batteries, and an 18 Amp-hour battery connected to a solar panel.
We don't keep enough in the fridge/freezer for us not to be able to consume it all before it spoils, although heating the frozen TV dinners will have to be done without the microwave. :->
My big deal is medicine. We're both on life-long pills, and if there's no long term power, we will have trouble getting prescriptions filled. I think I'll ask the pharmacy what their power plans are if there's an earthquake or long term power outage.
