Thanks! The photo was taken from a bridge over the river and I'm pretty sure that the guy in red was just a random tourist who really wanted a life threateningly close picture. I'm more comfortable with this distance.
It's not as dangerous as you might think. Alligators and crocodiles are lazy and wait for their food to come to them. They don't chase. Here's a picture I got of a crocodile, up close and personal: [link]
