Street luge is an extreme gravity-powered activity that involves riding a streetluge board (sometimes referred to as a sled) down a paved road or course. Street luge is also known as land luge or road luge. Like skateboarding, street luge is often done for sport and for recreation.
A longboard is a surfing variant of a skateboard, similar and related to a surfboard or snowboard with wheels. It is used for cruising, downhill racing, slalom racing, sliding, and/or transport. However, most stunts, and the boards themselves are very different from that of a typical skateboard. They usually are designed for the descent of a hill, slides, carves, manual or "dancing" with the board.
