What a difference a day makes:
Yesterday I was late to start, it was raining, headwind, and I got a flat. Walked back home (faster than changing tube) grabbed another bike and then crushed it all the way to work. Had to pass the Bike to Work Week celebration station and pass up on snacks etc. There was about the same amount of bike traffic: probably less commuters because of the rain but more because I was running about 20 mins later than usual.

Today: sun, calm, fast and fun. Stopped at 2 celebration stations and everyone was in a good mood.

Today: Sunny
