This is a cool, older video featuring four of the early American pioneers of Bigfoot research: Rene Dahinden, Peter Byrne, Grover Krantz, and Ray Crowe. Rene, Peter, and Grover are three of the "Four Horsemen of Sasquatchery." The other one being John Green.
These are the first big-time players in the field. Though the Native Americans had stories of Bigfoot-like creatures long before the white man ever stepped foot on American soil, these were the first Caucasian North Americans to take a public scientific approach to the subject.
