It was only a level III rapids, which isn't very high (from what I understand). There was a couple of times where it felt like we'd been swamped, but I never actually thought I'd fall out, or that we'd flip. Although, my paddle did catch on a rock once and I almost lost it. I forget how many rapids we went over, but they had names like Lion and Killer Rock. The company had a photographer on hand to take pictures and sell them back to us, so we all chipped in on a disc of >200 pictures. I've pared that down and you can see ones of (mostly) my boat. I'm in the back, on the starboard side.
