From Cryptomundo comes this interesting YouTube video which supposedly shows a Bigfoot sprinting across the background.
YouTube user jnctv1001 posted the following video titled:

SOUTH DAKOTA Bigfoot Sighting 2012

The reaction of the witnesses seems and sounds authentic. They’re watching a tall humanoid sprint across a field and, according to the YouTube information, ran into the woods. Disappearing from sight. I’m sure this will be compared to the Memorial Day Bigfoot video, which has been studied and analyzed by experts.
