Energysmackdown.com harnesses a healthy competitive spirit to conserve household energy. What about doing this on our streets and highways? How about a Mass Pike vs. I-93 (or more comparable freeways) smackdown, coordinated through WBUR 90.9 to captive NPR-listening commuters on their morning/evening routes? The goal being to measurably reduce traffic on our major feeder arteries, shunting people to public transit. Bonus points for increased bus ridership on the freeways or streets. We could choose a single day or week, or maybe go-green fridays. Go Metrowest! (that was intended to rile up the other burbs).
