Beautiful ride in. Had the satisfaction of pedaling right past the queue of cars immobilized on the BU Bridge. Of course I then had to contend with the notorious intersection at Comm. Ave, with its crowds of BU undergrads trundling off to class (many of them oblivious, being plugged into their mp3 players and smartphones). Some of them might be my students, and I'd rather not be recognized; so I had to play it cool.
