Would have been a perfect commute had I not gotten a late start and then a flat tire 1/3 of the way in to work. Made me slightly late to work, had to play a little catch up. 39*F, no wind, sweats, T-shirt and a light jacket were perfect.
Ride home was sporty - intense traffic, bit of a headwind, 60*F. Otherwise, pretty good.
Got some grease on my Brooks saddle when I changed the tube, darn it.
