Or an extremely large alligator gar....
You think youre kidding. Not far north and just to the west is Kenosha, WI. Multiple times alligators have appeared there. Most are small but in the late 1800s a 12 footer appeared. They obviously don’t really belong here. The theory at the time was that since circuses travelled by train and because multiple circuses over wintered in Baraboo then it stood to reason that one of the giants must have somehow jumped off the train. The thing is, the circuses have stopped running through there long ago yet alligators continue to occasionally appear. Just a couple of years ago a deer hunter was out near the swamp and stumbled across a 4 footer. Not a giant but Id still rather not get my foot caught in that.
