I don't know how many has seen this video, but it sure looks authentic to me. Now the bfro, got it off of u-tube and there trying to find the people that took the video. What happened was a couple of guys were floating down the McKenzie River in some row boats, and the filmer was concentrating on the other boats, when all of a sudden there is a sasquatch that is near the river that stands up and walks away.

It looks authentic to me. The reason I feel that it maybe authentic is that the camera man, is focusing on the other boats, and doesn't realize what had just happened.
Very interesting to say the least.....check it out.
