Skateboarding is always entertaining for those of us who have zero capacity to glide gracefully, let alone jump, with a wheeled artifact, but one local skateboarder has captured our attention and our unending curiosity. A mysterious skateboarder dressed like a skeleton, known as Ribs Man, has become the Banksy of the skateboarding world, at least in the sense that nobody knows his, hers or their true identity. Over the past four years, Ribs Man has earned a huge online following by posting videos of his skateboarding prowess as he wheels around — and above — Dallas. Ribs Man's identity has become a tireless guessing game for the skateboarder's followers, but it's a secret the skeleton will likely keep in the closet.
