I live and work in Cambridge, MA. In my opinion, Cambridge and Somerville are not very bicycle friendly due to the fact that main streets were laid out before cars were common. As a result, there is basically only one route (via Beacon) to work for me via bicycle. Grid-cities like SE Portland, OR where I formerly lived, were much easier because you can ride on a street parallel to the artery, not on it. Its nice to see what Cambridge is doing, but its a much harder job than other cities face.
