SIDEWALK SURFING

"Late 1940s - early 1950s Surfers California saw the bright idea of strapping roller skate wheels to a wooden board... to surf concrete when there where no waves. Whoever was the first to come up with the idea is unsure, it seems multiple people have been working on the same idea at the same time. Wooden boards with roller skate wheels strapped to the bottom... Skateboarding was born!"
