I Respond: I have MAXIMUM respect for Shamu's trainers. I would go so far as to say they have the most EXTRAORDINARY jobs in any theme park.
There's that point in the show where a trainer goes under water and and one of the KWs comes up behind him and they burst through the surface with the trainer perched on the animal's nose. The trainer goes into the air and dives back into the water.
Okay, to complete that manuever the trainer goes underwater and at one point has to look back over his shoulder and see this creature the size of a bus coming right up behind him.
How exactly does Sea World reprogram that trainer's most primal DNA to make certain that when he is flying through the air he is not screaming like an eight-year old girl?
BTW, the water for the killer whales is kept at 52-55 degrees. We had full wetsuits, but it sure was cold when water spilled in at the neck.
