Each September, hundreds of professional artists participate in Paint Louis. The annual music and graffiti festival brings people to the riverfront to pick and paint a two-mile section of the downtown St. Louis floodwall — also known as the Mural Mile. Part of the Paint Louis festival is “Paint Littles,” an area expressly for kids where they get to spray their masterpieces on the walls of an abandoned weigh station building. STLPR audio engineer Aaron Doerr brings us the scene.
