NY, I hear you. My last job, my office was 26 miles away, plus, I was driving around to clients anywhere from 11 to 30 miles from my house. Highway driving could not be avoided. I did cancel due to weather once last year and once this year. But, once, last year, I was at a client's home near my office and i looked out and it was snowing lightly. By the time I was done, I endured a miserable 25 mile commute in 2-3 inches of snow and more heavily falling, with little plowing on 495, as it was just too crowded with cars. I was able to get off the highway and drive through one city and 3 towns before getting home.
When I was teaching, my last job was 13 miles, and before I moved, 6 miles away. Of course, we didn't have school when it was bad. But those drives in snow never bothered me either, just going from one small town, through another, then home. However, when I first moved to MA, I lived 40 miles from work at one point, then 20. I had a few harrowing drives home when snow had started during the day, on that 40 mile commute, in the 90's. I suspect now, that school would have been cancelled in advance.
