So far as I know, not in a place where you, personally, could follow up and verify. When I was investigating reports for a not-to-be-named group/site, I had access to the raw reports. The woo stuff was in the raw reports but deliberately omitted from the published version the pubic had access to. This was done in an effort to appear scientifically credible rather than bat "guano" crazy. People seem a bit more willing to risk ridicule today. Even Matt Moneymaker talks some about the woo in reports that go back decades now. He was among the worst of the worst for filtering not so long ago.
MIB
This is where I'm at as well. I have done probably as much research as you have, which has mostly been listening to those with direct experiences. Sure, many of them are merely sightings between them and biggie somewhere in a forest that was nothing more than a chance encounter.
However, there are now plenty of cases where something paranormal was involved and I cannot ignore them because I am too stubborn with holding to my own theory. At some point I had to stretch my mind into a new area where it didn't want to go.
I think probably a lot of bigfoot enthusiasts are hobbyists who have casual engagement with the subject once in a while. But there are those who are more actively involved and devour as much as they can find and who keep their minds open to new content along the way. This where I am.
Supernatural:
If there is a world(s) "beyond scientific understanding or the laws of nature", we cannot describe it, identify it, locate it, understand it, or engage in any other level of interaction with it. If that is where sasquatches live, there will be no "discovery". Ever. It would be impossible.
