The Hillside Flyers are kids who tumble. But that's only part of the story. Many of the Flyers come from the poorest parts of Duluth, and they don't go to music lessons or summer hockey camp. Some of the kids have problems at school and at home, and tumbling with the Flyers is the only thing they believe they're good at. And they ARE good. Minnesota Public Radio's Chris Julin has this story.
