All of you going to think I am crazy, but actually moved to Colorado 3 years ago to just surf rivers from the Ocean. Grew up surfing the reef breaks of Hawaii, California, and Caribbean, from Pipeline to epic point breaks, but have more fun searching out inland waves in the arteries we call rivers. I have found waves in irrigation canals and in the middle of no where, its like the stoke and adventure of early surfing days all over again. Plus I don't miss sharks, aggro trendy pop culture crowded line ups of kooks who think their too cool. So to answer the question, I mostly use a rockered surfboard and works fine.
