I'm actually a physicist by training (don't believe in ghosts, telepathy, crystal energy or any of that woo-woo shit), so I was pretty convinced when I went on the first expedition that it was all a con... boy, was I in for a rude awakening.
Imagine the scene...
Something is moving in the bushes about 50 feet from me...
It's midnight, and there's no way anyone could be moving around in the dark without nightvision goggles AND IR illumination, because I have GenV nightvision and I can't see shit without the IR light turned on... and I can't see anyone elses IR illumination either...
...it must be a bear...
The "bear" then pulls over a deadstanding tree and proceeds to smash it to pieces... takes him about 10 seconds...
Then there's half an hour of silence... the "bear" doesn't move, sniff, nothing for half an hour... I still can't see shit through the nightvision...
Suddenly the "bear" sets off across the ridge in front of me... smashing branches every couple of metres... only thing is; I've walked through that area in daylight and there are no branches on the forest floor in there... just grass and deciduous trees, he must be carrying the branches with him... (the next morning I found mossy pieces of the smashed tree all along the creepy four foot wide "animal" trail on the top of the ridge...
As the "bear" passes closest to me on the ridge, it stamps its feet... three times in succession over the course of about 2 seconds... I can understand a rearing bear flattening down onto all fours making TWO stamps, but THREE???
The "bear" also covered 30 maybe 40 feet with those three steps and sounded much, much larger than any black bear... there are no Grizzlies in Wisconsin... and this thing seems big, even for a Grizzly...
More branch breaks... moving at such a pace that whatever is doing it must be hitting 30 miles an hour...
Then, whatever it is (which again, is still moving about without any visible or IR illumination) used a big branch to make a Mark McGuire-style home-run whack against a tree... a wood-knock that was so loud it actually silenced every noise in the forest for miles in every direction.
No more activity (except heavy bipedal footsteps circling my camp) till about 3.30 am... when a really, really tall "person" stepped over my tent.
Scary shit...
