I stole these words from Mike at Gravity but they work…

Go Skateboarding Day originated as the day for skateboarders to have fun, to raise awareness about the issues we face; to show the world what skateboarding is really all about; to reclaim our culture; and to define skateboarding as the rebellious, creative celebration of independence it continues to be. In the years since that first celebration, the holiday continues to grow, but the mission remains the same: Have fun, go skateboarding!
