COLD!!! I didn't notice it while biking w/ my kid to his kindergarten. I did have the presence of mind to be nervous of people driving around the neighborhood w/ frost all over their windows, but the temp itself didn't finally register until I was rolling on the MUP full-speed. Shorts were OK, but I *really* should have worn full-finger gloves. So my hands told me anyway when I tried to get them functioning at work.
