A good rule-of-thumb is:
Florida + Puddle = Alligator
I played a round of golf at a course in the Florida panhandle with a guy from the midwest. He hit a ball in to the water. There were signs warning golfers to not go after balls hit into the water. He ignored it because the ball was sitting on a log sitting in about 6 inches of water. He reached out to get his ball and got a very toothy greeting from the “log”. Dude ran to the cart and wouldn’t get out of it. He just rode for the rest of the round.
