Bigfoot buffalo yellowstone
Would you risk death-by-buffalo to pull off a Bigfoot hoax? In the following clip taken from a webcam at Old Faithful Geyser in Yellowstone National Park, we see four big, furry somethings (Bigfeet?) approach four buffalo in Yellowstone National Park. Well, one of them does; it's unclear what happened to the other three! All of the lit. on these critters has them just "disappearing into thin air"...
