This video caught my attention on youtube, not because the costume is believable, but because of the circumstances surrounding it. The photos were taken near a set of railroad tracks, presumably in the Hudson Valley. Notice the person pretending to be a bigfoot, is hanging out where a passenger train can see them. Is this a hoax being set up for passengers on the train? The short answer is "yep". The Beacon Bigfoot site, which has been exposed in the past, is responsible for these images, which back in April they presented as real.
