Sometime in the winter of 92/93
One day hit -37 F in Middlesex and -43 F near Johnson, where I was driving to. My car was an old Subaru DL with a heater that could either keep the windshield clear, or my hands warm. I figured seeing the road was rather important, so the windshield it was.
Halfway through, it started snowing inside as my breath condensed against the roof of the car. Fun trip...
