This video aired on the History Channel and was uploaded last year on Youtube. It shows a very large creature in a steel cage somewhere in a wooded area. The video depicts something hairy, large and walking upright.
The creature can be seen squatting in the cage than stands up and walks towards the cameraman. It than rattles the cage and tries to break free. There are many of the videos on Youtube of this Bigfoot.
The video here was the chosen one for this website because is shows the beginning, middle (when they tranquilize it) and the end (where it vanishes). Just try to ignore the commentary.
I am leaning towards the fake side and am a little disappointed with the History Channel.
