Sometimes, the biggest skeptics of all are from within the Bigfoot community itself. Every photo that gets published seems to get are weighed, measured, and scrutinized to hell and back. The latest image to succumb to such measure is the "Trapper" Bigfoot photo from Alberta, Canada. A few blogs that we know of are saying it's probably a bear's rear end.
"Misidentified game cam photo. this is most likely a bear with it butt in the air and it head rolling on something." - The Crypto Crew
"It's my opinion that this is a photo of the rear end of a bear. Subject to the right is a cub. The bear could be digging, scratching it's face, rubbing, cleaning or playing with the cub." - SasquaiNation, via Bigfoot Evidence forum.
