It's cold out. Today when I started my car (and I didn't think it was going to start), my temperature gauge read -15 degrees. It's cold out.
Side note: It is at this time of the year when I become severely addicted to caffeine. It is so hard to drink water when it is this cold out. Drinking cold water when you are already cold doesn't help your cause, but jacking yourself up with caffeine seems to have a warming effect.
