The only problem I have had with water slides was when I was little and at Waldameer. The Bermuda Triple slide tower thing. I was up for the middle one and asked the guard if it was okay if pushed off, he said it was okay so I pushed off and before I knew it "HI" to the top of the slide then in another instant I slammed on the slide nearly at the bottom. needless to say I don't push off anymore Man did that hurt. Last time I went they had a big sign that said no pushing off. I can't find a pic at the moment.
