Say "Chattanooga" and the first thing most people think of is Choo Choo. Not me. I think contemporary art, beyond the Hunter Museum of American Art. Two sculpture gardens: one in the Bluff View Art District and the other is a short bike ride away: Sculpture Fields in Montague Park, are both worth a visit. But there's art whether sculptures or murals along Main Street or MLK Boulevard or in several smaller galleries all over town. This YouTube video slideshow is a window into Chattanooga's edgy art scene.
