Found!

So, it looks like Akusai and Eib were looking in the wrong state. I was driving through northern Illinois recently, when I discovered clear, unambiguous evidence of a heretofore undiscovered Bigfoot civilization! See for yourselves:

As you can see, the noble Sasquatch is much more intelligent than previously suggested. While silly cryptozoologists were wasting their time looking for droppings and hair samples in the forest, they should have been looking through private school brochures.

The next time I have a chance, I’ll see if I can take some more pictures. Of particular interest was the Bigfoot Cemetery down the street. I wonder if Harry Henderson is buried there.
