that water looked green not white to me! kidding that looks like a lot of fun - years back we went out to the snake river in wyoming and went on an all day rafting thingy it was a blast i would love to go again - tn has some really beautiful rivers too ive never been rafting there but i try to make it to pigeon forge at least once a year - and yeah gopros are nice i have one with an underwater casing and take pics in the pool all the time - audio a little weird underwater on them though
