Skateboarders around the globe celebrate the 10th anniversary of "Go Skateboarding Day" by blowing off all other obligations to go skateboarding...

Go Skateboarding Day is This Friday June 21!

It’s been a growing tradition over the last ten years. Every June 21st skaters around the world flood the streets of cities and towns, much to the chagrin of local law enforcement, to revel in their sport and ignore responsibilities and city ordinances. Organizers say, “This is just one more reason to blow off your television/computer/video games and go skateboarding!” Credit: Jesus Solana

The Smithsonian Welcomes Skateboarders for Go Skateboarding Day Even the Smithsonian is taking notice. This year the National Museum of American History will be hosting a public festival complete with a mini-ramp built by CA Skateparks facing the National Mall. The Lemelson Center will announce its new project to start a museum collection of skateboarding history to “celebrate skate culture’s widespread innovative spirit.”

A little history... Jay Adams, Credit: Glen Friedman

In the 60s and 70s, skateboarding competitions that had been the purview of preppy, clean cut kids. But in 1975, the Z-Boys arrived on the scene and created an uproar. The Zephyr skate team from Santa Monica broke the mold and laid the foundation for modern skateboarding both in technique and attitude. They were surfers who took up skating in the winter and they used skateboards to practice their surf skills. Their surfer style blew away the competition and helped make skateboarding a worldwide phenomenon.
