D.C. #2?
D.C. may be #2 with respect to the number of commuters who bike, but it is hardly a bike-friendly city. There are virtually no bike lanes and the traffic is horrendous. While it is fairly easy to get around on a bike once downtown, commuting there particularly from the 'burbs is nightmarish. While the Metro and other transport systems allow bicycles, they do so on off peak hours thus discouraging commuting. While D.C. is a lovely place to bicycle, it is hardly a bicycle commuting nirvana.
