I use the D.C. bike map a lot—-I especially appreciate its ratings of streets’ respective suitability for riding. (E.g.: 14th Street NW north of Thomas Circle is splendid; south much, much less so. But wow, is Ride the City’s route tool for New York City awesome. Put in your starting and ending points, and it’ll calculate the safest route, a safe route, or the quickest route. Just thinking out loud (or as I like to call it, “blogging”) here, but what would it take to get something like this fired up for this area?
