The act of strapping a skateboard to a trash can or recycling bin, by means of a cord or duct tape, and riding in the bin down a hill at rigorous speeds. During rolling kayaking, it is crucial to have a long stick(such as a hockey stick) to paddle with, similar to what a rower does. Depending on the terrain, extra padding may be required, such as a seat when tearing it up on the hardcore ramps. For experienced roller kayakers, try iced-down surfaces for extreme thrills.
The most exhilirating sport in the world where basically a kayaker puts his/herself inside a small boat made out of plastic than continues to hurl themselves down rapids. It is highly enjoyable. Its way better than flatwater.
