Not entirely true. Black bear remains generally are seldom found just lying around. As I've said, I grew up in a bear preserve. We had MANY bears and a few big cats ... cougar and bobcat. However, if you just took a walk around a random hillside, you'd be FAR more likely to find cat skeletal remains than bear skeletal remains. If all you had to go on was bone finds, you'd think black bear are about as rare as bigfoot. Not the case. The reason for this is their near-death behavior. Cats seem to lay up in places where they can see around them when sick ... little knobs and open-ish hillsides. Bears, on the other hand, seem to crawl into the deepest, thickest brush around for cover. It reflects the defensive orientation of their kind ... some "see and flee", others "hide".
In the years I lived there, I never found a single bear skeleton that didn't have a bullet hole in it. The ones that died of natural causes did so in concealed locations.
We don't know what bigfoot's habits are when deathly ill, suffering organic breakdown at end of life, etc. It might be interesting to read up on great apes ... I haven't so I don't know what you'd find. Just thinking out loud. We don't USUALLY find human remains just lying around, either. Only those of people who die alone and by accident. If you and I were walking down the street and you had a heart attack and died, I wouldn't just walk off leaving you there while I went for a latte. If BF is the human megafauna I think they are, the situation may be the same with them, same treatment and respect for their dead.
It's just a guess, but as I've said, I know they exist, I've seen them. But .. I haven't found their skeletal remains. Must be a reason. I'm not automatically assuming some woo thing like I guess I'm supposed to according to scoftic agenda, I'm looking at the documented habits of the only proven natural biped ... us. It may not be the right answer but it's absolutely an option that has not been shown to be false yet.
