This video was uploaded by NvTV with not much information behind it. The description claims that a frightened camper in New York videoed this female bigfoot in 2013. I'm not sure how they determined it was a female, but if the footage is authentic, it's pretty impressive.
Update: In the comments section, NvTV said this:
This footage looks like its too good to be true...As this Female Bigfoot with an infant on its back just walks by this Lady (camper) who pulls out her cellphone to film it quickly before she takes off running. Some have said this is a hoax and nothing but a guy or girl in a Bigfoot costume walking in the forest....But if this was a HOAX why film it for only few seconds? I mean that's alot of work for a few second HOAX with a infant on its back...Is this REAL or FAKE?...Let me know what you think?
