A skateboard is a device consisting of a board made of any material onto which wheels are attached and upon which a person propels himself. Roller blades are devices, similar to shoes, which fit the feet of a person and to which a series of rollers are attached in line. Roller skates are devices which attach to the foot of a person, similar to a shoe, and upon which four rollers are attached in a rectangular configuration. All devices having rollers fastened to a shoe or board constitute one of these devices, i.e., a skateboard, roller blade or roller skate. (Ord. 603 § 3, 1997)
