Today is my last work day of 2010, and I'm finishing with 3530 miles bike commuting. Not as high as I had hoped for, but the snow, black ice and cold temperatures in December really put a damper on my riding. I finished the year in style, filling up my bike bags with gifts for my coworkers. Fortunately, the temperatures were milder this morning than they have been all month, about 40 F with very little wind.
