No, I'm not going to St. Louis for this, but, many (many) years ago, when I attended law school there, I remember riding this. I remember that it was such a blast, staying up late into the night and riding, with a great sense of fun and community, kind of an early 'take back the night' event (which they also had).
The bicycle is the most civilized conveyance known to man. Other forms of transport grow daily more nightmarish. Only the bicycle remains pure in heart. ~Iris Murdoch, The Red and the Green
