I made up my mind, several years ago, especially once I was retired (though I had the vow for the last couple years, while still employed, I must confess) that I would not drive anywhere when it has or is expected to snow. When my wife and I might be considering an excursion, I check the weather all the way west to the Dakotas, and if anything serious, or even lightly serious, is headed our way, I do not go on the trip. Period. I don't even make local trips in the snow.
For example, today, I kept an appointment at our church to meet with our priest, at his request, for 2pm. The weather was grey and cold but clear. So, I kept that appointment, which I had said would be conditional on the weather. By 2:30pm we had concluded our conversation, and the snow had begun. By the time I exited thru the front door, the porch and steps were slippery enough with approx. an inch of snow, that I had to hold onto the railing on the way down the stairs. I drove immediately and comfortably homeward, while the snow quickly fell. I parked the car in the garage, leaving it there for the duration of this storm. Nothing will get me to drive out in this snow. Period.
