I moved to San Diego about a year and a half ago, but prior to that I lived in upstate NY and then Washington DC.
Upstate NY is the snow capital of the country (outside of Alaska), so I was accustomed to several feet of snow a year, often a few feet on the ground after one night. We usually had school and work. But this is expected. It happens every year, so we had all the necessary equipment, and most people living there knew what to do.
DC, on the other hand, nobody has any idea what to do in this stuff, because it doesn't happen that often. Once in a great while there is a blizzard, but usually its no more than a few inches at a time. I was the only person I knew who lived there that actually had snow tires. They don't invest in what they need because they don't think they'll need it.
Then this stuff happens and the city is crippled.
That said, I've never been happier to be on the opposite coast.
