It's a emperor with no cloths deal with these groups
Look at the colossal failure of the nawac to put forth anything of scientific value. Then they cobble together that terrible monograph full of stories and pictures of rocks and pretend its science.
Several here have claimed amazing interactions, over the years. The surest way to offend them to feigned outrage is to ask for a modicum of evidence of their fantastic claims. Happens every time.
Any rock thrown for 400 yards would have to have a lot of velocity, enough to probrably put a hole in the roof. Small rocks wouldn't make it that far unless they were shot from a muzzle loaded gun or something.
Why do hoaxers have to be in cahoots? And how do you know that the hoax goes unreported? I'm sure there are plenty of hoaxed tracks that get reported by the person that hoaxed them. That also explains the whole " no one could possibly be out here" nonsense.
Also, some alleged bigfoot prints can easily be tracks left by a known animal and mistaken for bigfoot tracks.
