As part of my 2012 Southern States Tour I took a boat tour of the Atchafalaya Basin. We toured around the swamp and saw hundreds of alligators, some of which our tour guide threw food to, getting them to come closer for our photos.
We actually saw people on small 1 person boats fishing. God knows what they would have done if they had fallen in. We also saw two tourists who for some reason had abandoned their boat and were wading back to the shore. I guess it must have been on the way out into the swamp that they broke down, if they had seen the number of alligators I had seen they would never have left the boat.
