Just finishing a serious snow day here in Toronto with over 60cm (24in) of snow and windchill temperatures in the -20c to -33c range (-4f to
-27F).
When I see people crybabying about a mere foot of snow and barely sub-zero temperatures I shake my head. Around -40 (c or f) is when it gets interesting.
At -55 it becomes life threatening. Your eyelids want to freeze to your eyeballs and you have to move fast. I remember running into a truck stop and when we opened the door a giant cloud of condensed ice crystals filled the outside air. Indoors, it was like someone had used a fog machine. You could see the tabletops but everyone was hidden by fog from the waist down. That was cold.
