I bought a book called "strange wisconsin" a while back... there's so many little weird wisconsin local myths I can't even remember them all.
Up north we have the Hodag.. it's kind of dinosaur thingy
en.wikipedia.org/wiki/Hodag
We also have the beast of bray road, it's like a bipedal wolf but it's spotted periodically thoughout the north western bit of the state

This book is just short of 200 pages and it has a different story on everypage... we've got man-pigs, bearwolves, werewolves of several varieties, gnomes and leprechauns, and someone even sited 'aliens that brought pancakes with them'... and lets not forget goatmen or the numerous crazy ghosts (including one that is an animal and guards a pet cemetery) I love it here but I think wisconsin might take the crazy cake sometimes xD
