Brrr!

Temperature dropped about 15 degrees since last week, so I had my first frosty commute of the year. Took about 15 minutes extra to leave the house so I could find all my warm cycling clothes. After that, it was just another (fine, sunny) day riding to work.

Need to do it more, though. My knee gave me trouble climbing the stairs -- after one flight I gave up and took the elevator. But after a nice warm shower, no problems.
