Status: RealI know of many high schools named after Washington, Lincoln, or other famous characters from U.S. history, but as far as I'm aware, there's only one Big Foot High School. It's located in Walworth, Wisconsin. However, it's not named after the Bigfoot monster. Instead, it's named after an Indian Chief:
Big Foot Union High School is named after the Potawatomi Indian Chief Big Foot who lived along the banks of Geneva Lake until his tribe was relocated by the United States government in 1836. In fact, Geneva Lake was originally known as Big Foot Lake until a New York surveyor, John Brink, renamed it.
I can't find any reference to the Bigfoot monster on the school's website. I'm betting they try to downplay that connection. Still, it would be pretty cool to tell people you go to Bigfoot High.
