Consecutive bicycle work commute number 2251:
When I woke up Google told me the temp was -8°F. My kitchen thermometer told me it was -1°F. They are often a degree or two apart, but usually not by this much. I'm not sure what the actual temperature was, but probably somewhere between those two readings.
In any event, my first sub-zero bicycle commute for the season is in the books. Outside of my left foot getting a little chilly, it wasn't bad at all.
