It is a little more than that.   We are looking for something that does what we believe bigfoot does, where we believe bigfoot does it, when we believe bigfoot does it.    All we have to do is be wrong about what, where, or when and success becomes a result of fortunate accident rather than deliberate planning.   IF they are deliberately misleading us on any of those 3 "fronts", it takes an accident, not planning, to produce positive results.

Bigfoot DNA has to be different from human DNA since we homo sapiens have a unique genetic code. As far as I know we have never found bigfoot DNA that has to be way different from human or homo sapien DNA. The biopsy dart as Norseman brought up might be the only quick way to get bigfoot's DNA unless I'm mistaken. We need the DNA experts to chime in.    "Homo sapiens occupies a unique position in the history of life, representing the sole surviving species of a once diverse genus. Unlike chimpanzees, which have a close living cousin in the bonobo, or elephants, which include multiple extant species, humanity stands alone in the biological landscape. This singular status is a recent phenomenon in evolutionary terms, posing a profound question about how our species, which emerged relatively late, managed to outlast all its close relatives." internet search. Does this mean bigfoot is not a homo sapien?

I heard about such practices a long time ago, and wouldn't be at all surprised to hear they're being considered once again as the current administration continues selling/leasing federal lands. Wasn't it the movie Brazil that ends with people driving down a highway with either a strip of forest along each side of the road or billboards blocking any view but the road itself(its been decades since I saw it..) And as the movie ends the camera pulls back and up, revealing all the surrounding hillsides clear cut to the dirt?   I think I might well have done the same, choosing to not be a a part of the deception, much less a part of the machine that advances such destruction of forest and habitat.   I have read a number of accounts submitted by current as well as former Forest Service agents/rangers/workers over the decades of reading accounts. But realistically, you'd think that if they reported all they'd seen that there would be a whole lot more of such accounts. It would be fascinating were there found a record of all bigfoot/sasquatch reports submitted by park visitors to rangers of a given park, even unofficial, just the guys at the desk writing them down, if nothing else, for even "just" that could show actual numbers of encounters, possibly seasonal trends, maybe even give some insight to their numbers in the immediate area.

DNA always cones back as:   1) Contaminated 2) Bear, dog, bison, aardvark, or some other boringly known creature 3) or "human", and almost NEVER stated as "Homo sapien"
