If you are in or near Frederick, MD tomorrow you must stop for the Clustered Spires High Wheel race. http://www.highwheelrace.com
It really is the only bicycle race of it's kind anywhere. The winner is determined by how many laps they complete on a times course. The cycles range from vintage to new custom bikes made by the racers.
