This is a Bigfoot discussion board. A forum. Not an academic peer review research committee.
And I'm not here to prove anything to you or anyone else for that matter. An archaeological approach to Bigfoot evidence would require a site with known or suspected activity. Followed by surveying and mapping of the area, and if the situation warrants it, a field excavation.
Discussing a possible scenario regarding Bigfoot and cattle ranchers is simply thinking out loud. An educated guess based upon comparative evidence. This thread has nothing to do with archaeological research.
But once again, I think you know that and are simply trolling.
