As far as the BLAARGing thing goes, who knows? Chris might be one who actually believes the things he says (although I doubt it), but it's either that, or he's prone to whimsy and wrong. If seeing a BF were as simple as putting in time outdoors, many of us posting here would've witnessed them first-hand several times over due to our careers and hobbies, along with the alleged wolves and black panthers roaming the windbreaks between ag fields that characterize this region. And even in the case of a single person having exceptionally bad luck with regard to seeing cryptids in person, it doesn't near explain the dearth of accounts from our contemporaries and colleagues who also spend their lives outdoors.
In essence, to get to where Chris is at (taking his statements at face value) you not only have to believe the ridiculous notion that such a beast could exist and avoid detection all this time, but you also have to believe that everyone besides Chris and a few other 'knowers' in his region are either incompetent, too lazy, or too afraid to ever enter the woods and know for themselves. This list of lazy, cowardly incompetents would have to include professionals from multiple state and federal agencies, university biologists and researchers, professional wildlife photographers and videographers, full time hunting and fishing guides, and many others, yet Chris, somehow despite it all, sees bigfoots with with regularity. Oh, and he's got clear photos to prove it, but he'll only post the blurry ones.
That, actually, is probably a more ridiculous assertion than the idea of Bigfoot existing at all.
