Cold this morning, low 30's. My fleece vest/commuter jacket combo worked well. I also had my full finger gloves and skull cap. The amazing thing was that I pulled a thumbtack out of my front tire last night (not sure when/where I picked it up) but, even though it had pierced the tire all the way to the head of the tack, the tube stayed intact and leak free. Luckily this was in my front tire, an Armadillo, the back is a Continental street tire that I don't think would have fared as well. I was a little concerned about the potential for a slow leak over night or on my ride in today but that appeared not to be the case. I'll check it after lunch just to be sure.
