SWOT and IC, when I lived up in Rhinelander, WI, it was usually too cold for salt to work as well. They used sand, which didn't do much. And yes, at major intersections, you got polished ice.
We got clobbered yesterday with what passes as a major storm in the Milwaukee 'burbs: 8" of snow, some sleet and freezing rain, and very high winds.
I had to be out in it as I had a couple of appts I couldn't miss. It was nervewracking driving as it seemed like i was the only person on the roads who could both stop and start while maintaining travel in a straight line.
The winds were the worst of it as I drive a small SUV and we had gusts up to 60 mph. I took surface roads out and back as opposed to the hwy as nearly all of that is elevated and between icing and winds was more than I wanted to deal with.
Now? They are freaking out about the cold snap because it is in the 20s!
Me? I'm cranky because later today I have to go out, and I'm gonna have to chip my car out of it's cozy jacket of ice before I can drive it anywhere. We very rarely got ice in Rhinelander and I didn't miss it up there.
