Temps like that around the Great Lakes must be nasty; we get the cold but with lower humidity, which lessens the bite (a little).

Below -25C, vehicles get a little grouchy. Strong batteries are critical. If you have a winter weight oil (or synthetic oil) and can run the block heater/frost plug for an hour or two, starting will be easier and the wear-and-tear much less.

BTW, on the Canadian Prairies we're headed back into the basement, dropping from +7C/44F to -27C/-17F over a mere 36 hours. Aargh! The only difference (this time) is that there isn't a massive snow dump during the transition.
