 If you were out on a hot summer night in Minneapolis, you might make your way to the Stone Arch Bridge. It's a popular spot for tourists, students, and couples out on dates. And there on the bridge, you might find a guy sitting on a folding chair with his banjo, a white plastic bucket in front of him for tips. His name is Mike Sawyer, and he says these evenings out here are often his favorite part of the day.
