I don’t know, although, there is a creature of some kind. Its not Giganta Piccathus or the Extinct Large Ape. But, its some large mammal possibly the reminants of the Neanderthals. But, no bodies, no evidence ever collected to identify it definitively. So as far as Science goes just hair samples that indicate its a primate of sorts. I believe they exist all over the US and Canada but are reclusive animals.
