Congrats to Rick! The man is brave, you have to give him that. 112 feet up on a cable that's less than 1 inch thick, and the whole thing with no net! Now, I don't know how deep the fountain that he was walking over is, but I can guess that it'd still hurt quite a bit if he had fallen. Again, Congrats!
It's about 3 or 4 feet deep.
You can walk in it with waders on. That's how they used to put the fireworks up around the fountain.
