In an effort to get Charlotteans moving around the city without a car, Sustain Charlotte hosts this scavenger hunt where participants traverse through Center City and South End by bike, foot or public transit collecting stamps for their Biketoberfest Passport. The odds of winning a prize go up with every stamp acquired, so peddle hard and fast. Stick around for the after-party with live music, food trucks and more.
