=v= In San Francisco we promulgated the concept of "Waving Wednesdays." Basically, if you see a biker on Wednesday, wave! We even had the Queen Mum (R.I.P.) promoting the event online. =v= It was started by CMers, but the local bike coalition publicized it as well in its newsletter. Seems as if the same could be accomplished in Boston. <_Jym_>
