It was 9° F when I left this morning, -11° F with the wind chill. My eyes started to tear almost immediately and when the tear hit my riding glasses it immediately froze. Once I got going I warmed up a bit and my face was fine after that - until I hit the Roosevelt Bridge over the Potomac. The winds off the river were ferocious. I cannot describe how painful the experience was except to say that it felt like being trapped in a 7-11 Slushee machine - constantly battered and frozen.

All in all - a beautiful day for a bike ride!
