The Invisible Bigfoot?

I have been over on Mr. Nick Redfern's Blog titled Man-Beast U.K. He has an article there concerning the possibilities of bigfoot creatures becoming invisible. As strange as it may seem, this idea is nothing new in the realm of "bigfoot'in!" Anyone that has actively searched for hairy hominids ultimately comes across a set of tracks that are many in number and then dwindle in to almost nothing. In otherwords, the tracks seem to just fade away the further one follows them. On one occassion, I followed a set of tracks in muddy soil straight into an alfalfa field only to reach the middle of the field to find nothing. It was almost like the bigfoot floated off of the planet. The tracks just stopped!
On another incident, me, Wayne Murphy and Sherry Malin (both researchers from Tennessee at the time)came across a blonde bigfoot that was standing upright. Then it walked behind a large pine tree and disappeared. How does this happen? Is the cleverness in which the bigfoot hide their tracks far beyond our understanding? Are they beings that can play some sort of "Jedi mind-trick" on their viewers? Could they be extraterrestrial? Is it possible they travel through time portals? Maybe the archways and tree markers are much, much more than we think?
If you haven't read the book "Hunt for The Skinwalker" then you should. If you believe in George Knapp's story about the remote paranormal ranch in Utah (which I do) then bigfoot tracks appearing and disappearing become more sane theory if you will. This Uinta Basin ranch is claimed to have time portals, innerdimensional beings, bigfoot type creatures, UFOs, orbs and high poltergeist activities on a daily basis. I guess my last question would be "is there any other place or places like this on our planet?" It is conceivable that those type places could be in our own backyards...
