We've been having it fairly easy this winter, tonight is supposed to get down to the coldest for the season, around 0. Seems pretty bad until I remember last winter where we had a cold snap toward the end of January where it got down to below -20°, so in comparison 0° for one night doesn't seem so terrible after all! Provided my car starts tomorrow AM that is, it seemed to be acting up for a while in November into December like the battery was weak, so even though its been fine so far since the beginning of the year I still am a bit worried.
BTW if you hit Alt 0 1 7 6 on the keyboard right side number area it will type ° so you don't have to substitute using an asterisk. Not sure if there is a way to do this on a phone or tablet though?
