Tethered Riverboarding? What is it? Put in their own words, riverboarder.com say "Tethered Riverboarding is the art of surfing a permanent swell or pocket in the rapids of a river." Like the sound of it? Click on the website links below the pics. Riverboarder also offer a DVD showing riverboarders in action, along with some other cool sports like kite-surfing, etc. I have a copy of the DVD and it is pretty cool!! |
