Have you seen the sport of Riverboarding? Riverboarders ride small surfboards on rivers, going upstream at 30+mph. No Boat. Good riders can do Kick Flips, Big Spins, Shuvits, 1080s. You use the power of the river current to stretch a 20 foot long bungee cord. Using the river, this cord stretches to 200 feet! With all the snow we got this Winter, there is going to be lots of water in the rivers for riverboarding.
Riverboarding is a lot like wakeskating, but you don't need a $40,000 boat or $3 a gallon gas. Check out the video at www.bansheeriverboards.com This is a great Summer sport for Snowboarders.
