Don't know, Johnny, but a few years ago in the retirement community where I nowadays spend winters we had a 16-footer that used to hang out on the bank of the river across from the marina. That gator would have kept on growing, but some asshole fed him, and in gator country "a fed gator is a dead gator." They had to kill him. I've seen gators cruise by on Lake Harris that were rowboat-length. A few years ago this guy was hanging out on the Palatlakaha river as I walked by in the morning. He's a kid -- probably about ten feet.
As a lady on a tour I once went on explained: "A gator is very stupid. All he understands is that there are predators and prey. He thinks people are predators until a person feeds him. Then he thinks people are prey."
I've told this story before on here, but I'll tell it again since I'm a garrulous old guy: A few years ago in Florida I came rolling over a hill on my road bike and right in front of me there was a ten foot gator on the left side of the road heading for his pond, which was on the right side. I was doing about 20 mph and I figured I could whip on by behind him. Unfortunately he saw me and stopped, so I had to go in front of him. He opened his mouth as wide as it would go, but didn't try to grab me as I went by. I think he was as scared of me as I was of him.
