I biked down with my wife. Left at 10 am, got in at 11, watched the ceremony, home by 2 pm to watch the parade on TV and warm up our toes. We locked up right on Constitution and 21st. No problem with crowds, lots of portapotties, no cars on the streets. Rode on the empty highway for a while back home. Biking is the best form of transportation ever. I saw lots of cyclists, though it would have been more in warmer weather.
