Michelle, we went straight through a waterfall

So this is Ryland, Nana, and Papa on the Shipwreck Rapids ride at Sea World. To totally appreciate these pictures, you have to understand the story behind them. I'm deathly afraid of riding rides that have a potential to go really fast or make big drops. I also hate cold water. Anyway, I was fully aware that this ride did not fit the first two of my fears, however, I was 100% confident that I would not leave this ride without getting seriously wet with what I was pretty sure would be freezing cold water. So the first two pictures I took as the ride first began, at which time my mother was yelling, "Chicken, chicken" to me as I was snapping them. The third picture was at the end of the ride and you'll notice my mother's hair is not dry. The last photo was taken right as they got off the ride, as my mother is saying to me, "Michelle I saw this waterfall, and I thought there is no way that we're going straight through that"....as I'm laughing...."Michelle did you know that they was a waterfall?"
