Maybe, in a vast wilderness area. Like UFO's there have been too many credible sightings by law enforcement and military personnel, for it to be a myth or fabricated joke. If BF exists then they are smart, smart enough to bury their dead immediately so no remains have ever been found. But they have left sign deep in the forests from high tree scratching, foot prints, broken sign trees, etc...
I don't think they are common, but the first hunter that kills one will be a very rich man.
