Too many Californians here these days. This was not a blizzard. We got what? 8 inches of snow? I used to walk to school (uphill both ways) ;-) in worse and had fun doing it. I think that maybe it snowed more back in those days.
Colorado only just started using mag chloride.
We use to depend on good tires and driving skills on top of packed snow roads.
The roads did not need to be clear to the pavement.
