My second biggest fear with those enclosed slides. First is the water stops runnning and I get stuck. I am very claustrophobic and these enclosed slides terrify me! Even the clear ones. Actually, this is a combination of my two biggest fears, the tube cracks and water leaks out, so no water in the slide after that point and then I'd be stuck! Well, I wouldn't be stuck because there is no way in h*ll I'd ever go on one!
