Surfing Waves

i ran across this site, and its all about surfing rapids on rivers. pretty sweet looking. thought i might give it a try on the river we've got close to me. think it will screw me up when i get back in the ocean?

it looks cool but if you eat it your gonna get boned, all the times ive been rafting on those things i get thrown off to the point of almost drowning, i dont know though ive never tried to surf them, but i'd still try it if i lived there. good luck
