DC has some of the worst traffic in the country, which is one of the the main reasons I commute by bike. Traffic jams are such a regular part of my commute, I really don't take much notice anymore. I'm more focused on enjoying the ride. It doesn't seem very different here around the holidays traffic-wise. The days I have to drive to work, inevitably I'm caught and passed by several cyclists, never to be seen again. Now, that annoys me!
