I personally have pictures of deer, coyotes, black bear, racoons, porcupine, bobcat, etc. Others in NH have pictures of mountain lions. Yet the NH Fish and Game states there are none living here. Maybe they only pass through on their way to NYC.
My point, is how come there are not dozens of Bigfoot pictures on game cameras?
They are probably less likely to be found in more densely populated areas of human habitation. They likely need for forest for living than deer. Also, having such pictures, and having them all posted on the Internet are two different things. Here's a trail cam photo from Maine of something huge gathering apples:
Why would someone have pictures and not share them? People may be afraid of being mocked or accused of faking the picture. Others may think they can sell the image for cash, and so not post it for free, or be afraid of people coming on to their property to look for Bigfoot. Government employees may be afraid of retaliation or lack of advancement if they share things contrary to the official line that these are all just bears walking on two legs.
