The other thing to consider and we of European descent tend to loose sight of, in how to define BF is that almost universally the Native Peoples of North America consider BF a tribe of "people". They have coexisted for as long as Native Americans have been on the continent, and rather that some giant ape, scarey beast, as Europeans have tagged them, they are most often referred to as "forest or mountain people" or something similar by most native peoples. Often tagged with spiritual or supernatural abilities. Native Americans should know better than we what they are because they have been around them for at least 10,000 years.
