The Cardiel Rail is a monstrous 24 stair handrail that is located adjacent to San Francisco's Union Square. The stair set is on a hill which makes the handrail run at a weird angle and has a brick run-up and landing. John Cardiel was the only person to skate and roll away from this rail, hence the name.
