This is a funny card, but the Loma Prieta Earthquake wasn't a funny event. Anybody living in San Francisco at the time can tell you exactly where they were, what they were doing, and what they did for the next 24 hours when the quake hit. Parts of the Bay Bridge fell down, a two level freeway collapsed on itself, and the Marina buckled and then went down in flames.
I was eight months pregnant, and on the 20+ something floor of a high rise (does the word "skyscraper" every get used any more?). I had driven across aforementioned Bay Bridge not an hour before.
The city by the bay may be subject to unanticipatable earthquakes, but I'm still happy to be going home today after ten days in Washington, DC.
