Cobblestone Riders
Ricardo Marquez Invented a Skateboard to Surf the Tram System in Portugal
"The cobblestone streets of Europe are beautiful, but they’re a bitch to ride on a skateboard. Portuguese engineer Ricardo Marquez went after that problem with a vengeance, inventing this skateboard that could fit within the grooves of the tram lines. The board is applicable all over the continent, not to mention in places like San Francisco here in the United States. Nobody said they were safe… but safe never changed anything."
