Ah, I was wondering how your knees were holding up as I was heading out yesterday - it was chilly and windy that morning in my neck of the woods too, and stayed that way until mid-late afternoon. I kept my warm tights on for the entire ride.
It must have been beautiful up on Hamilton, though. It was so clear out that I could pick out all of the observatories from the Dumbarton bridge and even farther away than that.
