It was 22 F (-5C) this a.m. when I left. Lots of layers and except for the fact that a Buff in front of my mouth makes me crazy (I feel like I can't breathe), I was fine. It took 6 miles of a 7.5 mile commute for my finger tips to unthaw, but I expected that.
I also threw my light's battery charger in my pannier. I figure, it's dark enough that I really should enjoy the light of HIGH beam from my light, and if the battery indicator light should go on (signalling low charge), I could always charge it at work during the day. Fortunately, it didn't come on, and it will have plenty of charge for the ride home tonight.
