In Chicago this weekend? Naked Bike Ride on Saturday 13th

Saturday June 13th 2009
PARTICIPANTS: Check-in after 6pm near the "O" sign near 1077 W Randolph. People-powered wheels strictly required.
SPECTATORS: Come near Finkl on Cortland by Kingsbury before 11pm. Wave and cheer safely from the sides, behave yourselves, come without car.

I though Columbus tried to participate last year, but I never received any details about the ride. Ran across this while looking for things to do in Chicago.
