There are some at the Kennedy Space Center that could make a run at it since it’s a wildlife sanctuary. I’ve seen some HUGE gators there but nobody with a tape measure checking them. And even if they were record breakers, you can’t do anything with them since they’re protected. Except the one that decided to lie down at one of the gates around 0430 one morning and impede traffic. He was blocking both inbound lanes and one of the guards took it upon himself to pop him after about a half hour of trying to coax him/her to move. I think I was either 3rd or 4th car in line waiting to get in to go to work.
Biggest truly wild I ever saw was 17+ on Lake Monroe - two guys laid next to him head to toe, head to toe and that gator was still bigger!
