One of my favorite hobbies is Flowboarding. Flowboarding is a board sport that is performed on an artifical "wave" of water called a Flowrider®. A Flowrider® produces a sheet of water across a trampoline-like rubber canvas at around 30-35 miles per hour. It began in the 80's and it's getting very popular. It combines elements of Surfing, Wakeboarding, Skateboarding, Skimboarding, and Snowboarding.

I'm personally able to carve, spin, do pop-shuvits, 360 shuvits, 360 bigspins (shuvits while spinning), fastplants, and kickflips.
Are there any other flowboarders out there or is there anyone who's ever been on a Flowrider®? If you've never been on one, i highly suggest you try it. It is really fun!
