The MBTA recently decided to ban's ad calling out Senator Scott Brown for voting to gut the Clean Air Act--but we're making lemons out of lemonade.

Instead of running our ads at T-Stops, we're making sure our campaign is people-powered by hiring cyclists to tow these bike-powered billboards for five full days! But we'll need another few thousand dollars to get there. Can you chip in today?

Scott Brown thought no one would notice or care that he took dirty money and let it buy his vote. These ads will catch his attention and cause him to think twice the next time he takes dirty money and lets his vote be bought by big polluters.

Just imagine the reaction of Senator Brown's Boston staff when they -- and thousands of constituents -- see these ads at popular locations throughout Boston.
