I tried to watch the show for the first time (North Carolina ep) but after 10 minutes I was banging my head off the wall.
They don't know the first thing about proper investigative techniques; it's clear they have no clue about what they're doing. Ooh, someone heard a growly voice and don't know what else it could be? Apparently they've never heard of things called "bears" or "mountain lions" or "other large animals that aren't bigfoot." Sheesh.
That "blurry" thermal image of the candybar grab, if it wasn't a human hoax, was probably a bear.
I don't buy into ghosts either but the Ghost Adventures dudes have comraderie and a goofy charm that make them fun to watch. This bigfoot crew is crabby and unlikeable and have no redeeming qualities.
I'm with Jane Goodall - there's absolutely no evidence they exist, but I'd like to think they do. Having experienced the vast wilderness of British Columbia, its not hard to imagine something/someone able to avoid detection for generations.
I also live in original bigfoot country and also agree with Jane. For one individual creature to avoid detection would be plausible but not for a sustainable population of large primates living in the Pacific Northwest, or anywhere in North America. They can't all avoid detection for this many generations, one would have been shot by a hunter or hit by a car by now. Besides large primates have been found in tropical regions of Africa and Asia (humans had their origins in Africa), there's no real reason to expect to find a new species in temperate areas.
Though it would be exciting to find another large primate that is closely related to us, we could learn so much, not only about it but about ourselves.
