Was talking with Tom Bruni, who had planned to ride with Larry Black and others from Baltimore to Washington DC as a part of our 4th Annual National Mayors' Ride, and he told me about the Baltimore Kinetic Sculpture Race that just took place there!! It has been going on since 1999 and attracts entries from all over the East Coast! Here is their 2004 event:

And indeed there are some wild entries......
Tom, who owns Bruni Bicycles, has even begun to design a pedal powered submarine for next year's event!!
