Norseman,
You don't have to agree with MM to accept or consider that claim as possible.
The claim that BF are seen in almost every state of the Union is based on anecdotal reports collected from all those states (not just by BFRO, but also by other investigators and groups).
These reports are very similar in quality and description.
You can pick a report at random and describe the general incident without telling the State of origin - and many of them will sound very similar and not particularly location centric.
If you want to only accept the reports from PNW (WA, OR, CA) and reject those from OK, TX, FL, GA, SC, etc. then you are not being consistent on your acceptance of reports as evidence.
BTW, I don't like this observation either.
But, I won't reject it just because I don't like it.
I also do not like the fact that there is no physical evidence after more than 50 years of people searching for it; specially if you believe that these creatures are all over the US and Canada.
It is hard to believe that such a large primate or hominid could get away with living among us and not leave physical trace evidence or be already detected and documented by the hundreds of thousands wildlife biologists studying our fauna.
I don't put much evidentiary weight on footprints, stick structures, photos, sound recordings, or even DNA samples that were not taken directly from the animal itself (blood sample, tissue sample, hair sample).
So what do we get after 50 years of research? Not much but stories.
It is a mystery and it is not zoology or biology as many of you will like it to be. It is cryptozoology and the collective sum of the anecdotal reports don't make a lot of sense if the animal behaved as expected for a big ape roaming all 49 states + Canada.
Granted, you can discount the anecdotal reports, and then we got nothing.
I agree with others that the PGF film is not the key driver for the claim, but a side show.
IMHO, NAWAC is the only organization that is taking seriously the idea of collecting a specimen and are intelligently putting resources to that end. If they don't succeed with all those resources, then the nut must be very difficult to crack.
