You know what would be more believable evidence of spotting Bigfoot?
If you just take photos that show no movement whatsoever, even really "clear" photos (which may not be blurry, but don't show very much detail), your Bigfoot sighting looks an awful lot like a tree stump. (Just look at the shadows of the other smaller brush around it. Looks a lot like the Bigfoot shape, just a different size, doesn't it?)
If you then say, "Well, it disappeared before we could start taking video," then you should have included a photo that showed where it stood moments before.
