Skateboarding
Skateboarding is the son of surfing. One day a couple of surfers were tried of waiting for the perfect wave to ride so they did something different. They nail wheels to the bottom of there boards and that's how we get skateboarding.
Today we have all kinds of tricks and grinds. All the skateboarders from the 80's and 70's now own big skateboard companies. One of the greatest skaters of all time, Tony Hawk owns the birdhouse skateboard company. Tony Hawk is now a retired pro skater after doing his most famous trick the 900.
