how the hell could you forget the skateboard! its a board with wheels on the bottom! an object with four wheels used to shred on made popular by the zepher skate team, ex. alava Something else I was never good at but all my friends were. Skateboarding was a demonstration sport in the 1976 Olympics in Montreal; I remember seeing it on TV. A concrete skateboard park was built in my neighborhood in the late '70s but no longer exists. The first neon plastic ones with red wheels and flip tails. Like mini-surfboards. Half the size as the ones kids ride today. More durable too.
