It's been a while since I had to deal with negatives, but it got down to zero here a few weeks ago without factoring in wind chill. If all I had to do was walk home in the crap I could cope, but if I want to get work done I have to fool with frigid metal, and climb up to where it's even colder. I watched it go from freezing rain to a bit of snow earlier, and it's going to drop pretty close to zero here (without wind chill) in the next few hours.
