It was a bit cooler than I expected this morning (low 30's), and I mistakenly wore my lighter gloves. My fingers were a bit numb by the time I got in, but overall, it wasn't too bad. For some reason, traffic seemed a lot heavier than usual, though.
I did run into a fellow bike commuter in the elevator of my office building, though - which is a rare occurrence since I work in a pretty small building.
