If we've ruled out a bear, then the fact bears were in the area is irrelevant. If squatches are known to be in the area, then the possibility it could be one moves up a level.
To my way of thinking, the value of this photo is we've eliminated the probability (from what I've read so far in the thread) that it's a bear. Therefore, we need to eliminate the next plausible match, of which, a squatch is one, along with a primate, like a chimp, as you've suggested. If we isolate the chimp, it seems we'd want to figure out how it got there. This leads me to a question overall that might be known to the forum: how often do we catch animals in places they're not supposed to be on trail cameras, like when some idiot exotic animal owner lets them free or they escape? Do we get pictures of tigers roaming the woods in Michigan? Or Kangaroos in Washington? These are over the top examples to ask the question of do we actually get pictures of chimps in the woods, say in Ohio? Or do we say we know this happens, but we don't have any (or much) evidence?
