But, alas! One of the 1500 rings purchased by the city using funding from the Energy Efficiency Block Grant was installed this week in front of my office on Walnut. The first microbrew I drink at whatever Beer Week happy hour event I end up at after work will go to Mayor Nutter, the PPA, and the Bicycle Coalition for making this happen.
