Boy I remember that day. I was driving from Great Falls to Missoula via Helena. I had a bad transmission leak and had to put fluid in every ten miles as I had a warranty that was only good at the shop that did the work. It was so cold that my engine couldn't stay warm. My carb froze up and I stalled out at Carroll College I had to stuff Ollie my clothes in between the radiator and the grill so that I could block the wind and let the engine stay warm.
