When I lived in St Augustine, FL there is an Alligator Farm there. One day I was having breakfast next to a guy and we started talking. He was the Manager of the Farm and I said I wanted to visit it. So I got a behind the scenes tour of the place and got to see a ton of different alligator and crocodile species including seeing Maximo, the largest crocodile at the park measuring in over 15 feet.
I also did the zip line over the crocs (hey, I'm crazy like that! I do black water diving with alligators and snakes).
