Skateboards first came on the scene in the 1950's in California. A decade later, they were being produced and distributed throughout the United States. A skateboard is a board with four wheels on it that can pivot. A rider places one foot on the board and pushes it along with their other foot. Some riders can do tricks and ride half-pipes. Another version of the skateboard, the longboard, is longer and thinner, with softer, larger wheels.
