Is Bigfoot Inside The Treeline?

These are situations were Bigfoot researchers always think they see something moving. That is when you are in a clearing and think you see something moving within the treeline. Is it the wind? is it an animal? Or, is it something that may have been following you all along. The other day in field, I got that thought when I saw something moving. We must take many hours of this type of video and analyze it carefully to make sure something has not been overlooked.
