BOULDER, Colo. — The fate of this year's planned Kinetics event -- which organizers hope will happen on Boulder's bike paths -- is still up in the air, following a meeting between supporters and city officials Wednesday.

The annual Kinetic Sculpture Challenge event at Boulder Reservoir ended last year after 28 seasons, following a decision by KBCO to pull its sponsorship. Since then, small local groups have tried to keep the event alive. Last year, organizers held a scaled-down, land-based celebration in the parking lot of the Twenty Ninth Street mall.

This year, Kinetics-backers plan to stay on dry land. But in the tradition of the water-based craft that participants once powered across the reservoir, organizers hope the moving, people-powered craft can be piloted along the Boulder Creek Path.

They'd like to host a June 13 festival and parade, starting near Arapahoe Avenue and Cherryvale Road and finishing at 32nd and Walnut streets.

But city officials are worried about how event planners intend to avoid rendering the bike paths inaccessible to bicyclists and pedestrians. Wednesday's meeting "raised more questions than it answered," said Paul Bousquet, a spokesman for the city's Parks and Recreation Department.

Officials who serve on a city "event committee" want to know, for example, "how will you limit the width of the craft to accommodate two-way traffic, and to allow passing on the bike path if this were to use the bike paths," Bousquet said.

Jonathan Sterner, who represented event planners during Wednesday's meeting, said some of the city's questions were a bit overwhelming.

For example, he said, a police representative at the meeting was concerned that the bike path tour is scheduled to end at Twisted Pine Brewery.

"An alcohol-free event should not end at a brewery," Sterner explained in an e-mail to supporters after the meeting. "There is a concern about consumption of alcohol at the brewery and returning to the bike path or driving from the event."

But, he said, his group is committed to doing whatever's necessary to make sure it happens. Organizers and city officials plan to meet again in the next few weeks to try to iron out the questions that have come up so far.

"I told them, 'You guys have all the experience; We have very little experience,'" he said. "We're essentially Kineticists with no place to go. We're trying to create an event with no experience on how to create events. If you were to do this, how would you do it?"
