I have never been able to get to the end of the Fourth Borrow Pit Trail in Shark Valley.
I have always encountered a trail monitor like this guy.
I have read that you can scare alligators by waving your arms out from your sides and making a lot of noise -- perhaps making them think of the Great Blue Heron that ate their siblings.
And if they have eaten recently -- like in the last few days -- they are somnolent with digestion.
And if it's a cool day and they are in the sun, they don't like to move.
And so I could probably jump over this obstacle, but somehow in the middle of that dark place, it just did not seem like a good idea.
So once again, I turned around.
