I went to high school just outside DC (decades ago), and people in that region simply don’t know how to deal with snow. Two inches on the ground in the a.m. and schools got closed.
You guys don’t understand. No roads were treated in the DC metro area. The snow fell and turned into a sheet of ice during rush hour. I witnessed drivers on I 66 literally stopped at the top of inclines and taking turns on out of control skids to get to the bottom. It took some people 8 hours to get home.
Actually, maybe that's exactly how to deal with it.
I grew up in a place where it took a couple feet of snow to close schools, and two inches was just a winter day. We had the equipment to handle snow.
Then I moved just outside the beltway. In the few years I was there, we got a couple inches maybe two or three times a year, which would then melt off the roads in a day or two. Does it make more sense to have enough equipment to clear a lot of roads after the occasional snow storm, or to just close schools (and most of DC) for a few days a year and let it melt?
