To show my ignorance about this kind of thing, I thought the bigfoot was the one peeking around the tree at left and waving. Seriously. Thanks for clarifying.
Oh I'm guessing if you stare long enough you'll see whatever you'd like.
Since Chris won't discuss the circumstances surrounding his pic, it's assumed that this was done with the latest rage in Bigfoot research.
Go to your research area, which by the way Bigfoot is always right there waiting for you to show up. Then assume a 8-10' tall 500-800lb monkey man wood ninja has snuck up on you and start taking pictures.
Another great one is video behind yourself while walking trails, of course your bigfoot buddy is always just one step behind, and all this action is totally unseen in real time.....post expedition review of the footage is when the Bigfoots really start to show up!
Also lets not leave out the Bigfoot buddy in your backyard habitators, there are a whole group of these delusional researchers over at BFF. Their leader is a nuthag that goes by Sassyfoot, who is one of the "chosen" ones a very special knower with a Bigfoot connection. Their primary research technique appears to be and is really astounding, just walk out onto your deck and start taking pictures and of course go back in the house and let the discovery begin. This group just as Chris also claims to have the good stuff but won't release it...they also tend to believe in Bigfoot mind meld, bigfoot has pets, Bigfoot will follow you home all sorts of wacky poop!
Finally there's a group of people that appear to actually have some outdoor experience and encounter something the can't explain either in person or maybe a game cam pic. Their experience takes them down a rabbit hole of "I can't explain it....therefore it must be Bigfoot!!!
I myself have had this experince many times and the experiences range from unknowns in the woods, to ghosts and even an NDE, but my mind works with "most likleys" and it's most likley I'm mistaken, misinterpreting what I'm experiencing.
But this group of people tend to jump the shark on eveything they find in the woods, broken branches, stumps, any depression in the ground is a track, any noise is Bigfoot....always when one is Bigfoot hunting guess what they find

Here are some great examples of this mentality....these are all most likley

If you went over to BFF (Bigfoot Fantasy w/Friends) and made these suggestions whew the fun would begin....the one of the cow is a locked thread, no more cow discussion it must be Bigfoot!
I'd love for Bigfoot to be real it's a very romantic notion....the wildman living in the woods by his own choice, at one with nature.
But there's nothing I've ever seen or heard that can't be explained with a much more reasonable "most likley" as opposed to an imaginary monkey man.
Except of course River's theory now that requires further research!!!
