This is from LegendTracker - makers of a bigfoot cell phone app and other apps.
Here is there Youtube page http://www.youtube.com/user/LegendTracker
Here is their facebook page - https://www.facebook.com/LegendTracker - they seem to be lol'ing about how this video is making waves.
They are just making money and making fun of people who believe in bigfoot - or it sure appears that way.
So is the video of a real bigfoot ? I'd guess no
The above video has gone over 1 million views in about a week and been featured on many News stations.
