A group of urban activists known as The Mower Gang have cleared the half-mile Detroit Velodrome track of weeds, beer cans, and other trash that kept bicycles away for decades. “It’s really not about getting some 45-year-old guy a better place to ride his bike,” said the Mower Gang’s founder. “It’s more about getting 10-, 12-, 13-year-old kids a better place to spend an afternoon.” (freep.com, via Mr. Jalopy)
