This is cool, but a little suspicious (to me-the skeptic) as far as the caption goes. It looks more like a drainage tube due to the lack of everything that typically goes into a sewer...lol...and the high water marks on the side. Second, the camera is suspect as it's right in the middle, even if hanging down...so, whether a worker did it or someone who saw the gator going in and out or saw the footprints/drag marks...etc. and put it there...it might not live in a sewer...it might just be using the path of least resistance to get from point A to point B....We have several of these near me/my work and they've tried to put bars across them, and the gators simply go next to the tube and push their way under the underneath the chainlink fence...even when it's rebarred into the dirt. They uproot and bend the bars with no effort...it doesn't even scratch their armor. It's amazing footage...makes me wanna go look in the tubes around here...lol.
