Everyday around 6pm as rush hour traffic slowly rolls through the intersection of Montrose & Allen Parkway, a mysterious dancing rollerblader appears. Film school student, Juan Carlos of Spain says he's been dancing at this same intersection for 15 years. Exercise and entertaining himself is what got him started but he's quickly realized that his rolling dance moves have been uplifting for Houston drivers. He says he carries about 1,000 songs with him, everything from cumbia to salsa, disco and sometimes rap.
