I know it's serious. I know a lot of people are enduring things that are very difficult. But, I have to admit, as a survivor of some of Minnesota's coldest-ever winters, it's hard not to be just a little bemused by people prophesying doom on the basis of "temperatures expected to drop to as low as 11F in Houston and 9F in San Antonio."
I mean, in 1983, I once waited 30 minutes for a bus in -40F windchill temperature. They didn't even cancel school!
Vox Day goes on to offer excellent advice on how to handle the cold. A few years ago, we had -40C wind chill in Ontario. Universities, colleges, and schools were open! I had to walk to work. It hurt but it was manageable.
