Wendy Schneider’s recently released film, “Angels of Dirt,” is a true labor of love. The 90-minute picture focuses on Charlotte Kainz, who, as a child, embraced the male-dominated sport of flat-track motorcycle racing. One of the challenges, Schneider tells “Driven to Ride” host Mark Long, was explaining the rich history of this “go fast, turn left” form of two-wheel competition to a new audience.

While Schneider interviewed a number of top former racers, both men and women, Kainz is at the heart of the story. “This is somebody, who, at a very early age, was carving out her destiny,” she says. “Watching her emerge as a contender, who said, ‘I want to race a Harley-Davidson XR-750. I want to race it at the Springfield Mile, and I want to win.’ She was her own compass.”

Kainz was a force, says Schneider. “All of us who were friends with her over the years loved watching her become who she became. That pairing of this young person on this monstrous motorcycle meant something that was bigger than both of them. It was really quite beautiful to be around. Why not celebrate it?” Why not, indeed.
