About a dozen people running naked in Boulder while wearing freshly gutted pumpkins on their heads were ticketed last year for indecent exposure. No one was convicted but there was concern that under state law the streakers would be labeled sex offenders if they had been.

Hapa Sushi owner Mark Van Grack says he is handing out the orange undies because he's afraid the runners will be arrested if they bare all. It doesn't hurt that the underwear also sports the restaurant's name on the rear along with a reminder to "run responsibly."

More than 100 people took part in last year's run down Boulder's pedestrian mall.
