Move over, Bike to Work Week. Planning is under way for a mass naked bike ride in Madison on Saturday, June 19, as part of a worldwide movement, Or as one of the movement's slogans puts it: "Stop indecent exposure to vehicle emissions." The rides, begun in 2004 and the subject of two documentaries, are open to anyone who wants to celebrate "the glory of naked two-wheel sanity." Participants, some of whom may be on skates, blades and boards, are encouraged to decorate their bikes and paint their bodies. In Madison, "The exact route is yet to be determined, but will include downtown locations where people are likely to be out and about," says one of the local organizers, who declines to be identified. (Um, aren't you planning to reveal a lot more than that?) "I would guess it will be a loop of no more than five miles. I have been estimating participation to be between a dozen and a hundred." The start time is listed as 11 a.m.; the starting location is undetermined. Details will be posted here. A planning meeting is set for Sunday, May 2, in the UW Memorial Union Rathskeller, 4 p.m.; clothing is required.
