Until yesterday, I'd never seen a street sweeper quite like this one. I spotted David Musser on Route 5 in Batavia and when we spoke he said people around here often comment that they've never seen anybody propelling themselves down the street on a skateboard with a stick. Musser recently moved here from Chicago and said the sport seems more common there. Primarily, he said, it's good cross-training for stand-up paddle boarding on the lakes.
