There was a big win for Green Mobility this week. The Miami City Commission approved, 5-0, the Bicycle Action Plan offered by Mayor Manny Diaz to set the city on the path toward true bicycle-friendliness. We've been working for this since February, but to underline its importance we held a demonstration ride outside City Hall before the commission meeting. Mayor Diaz and Commissioners Joe Sanchez and Marc Sarnoff joined us on the ride, along with Police Chief John Timoney and several other city officials. Much remains to be done — both to execute the present plan and to create the public climate that will support broader and richer efforts throughout Greater Miami. Won't you help us bring it about?
