At least one thing I can say, I cannot see the point of doing biological research on Sasquatch if it is not purely a flesh and blood creature. I get it that so much mystery and unknowns exist, but if we allow that void to be filled with erroneous suppositions based on subject experiences, not objective observation, well we might as well just not pursue the creature scientifically, but in a more spiritual fashion. I am not knocking the notion, but you are definitely in one camp or the other whether you know it or not. It is simply inconsistent to be out looking for DNA and prints, recording vocalizations, et. of a creature that can shape shift, or pass through dimensions. That is not an inquiry of science, but of the paranormal or metaphysical. I have dabbled on that side of the fence, and know others as well who have done the same, some of what these so called Bigfooters are associating with these creatures is common to any pursuit into the supernatural. Apparitions, demonic figures, portals, cloaking, and in my opinion ET activities all fall under a spiritual nature, and I am not talking about the good witch of the west here. I would be cautious in opening myself to such influences as they seem good on the surface, but they pull individuals into dark places. The Hail Bob cult were communicating with the ET's before killing themselves to pass into that supposed realm. My experiences and experimenting was leading me to a similar place, you need to be careful what you allow in.
