"Cycling already has a foothold at many colleges, where hefty parking fees, sprawling campuses and limited roads make it tough to travel," the Associated Press reports. "Students say they like the convenience of having a bike whenever they need it. [Ripon College], outside Oshkosh, Wis., has spent $26,000 on its free bike program, which so far has signed up half of the 300-student freshman class, Damm said. Emory started a bike-share program a couple of months ago. It has just 20 bikes now, but that will double by this fall, said Jamie Smith, who oversees the initiative. At Duke University in Durham, N.C., the bike-share program started last year had to start a waiting list because all 100 bikes were checked out within just a few weeks."
