I love that video, I have watched it a couple dozen times. I like the Seahawks decal on the boat and the attention to detail as the beer he is drinking is a Rainier.
I think you posted this video a year ago or so. Did you ever figure out where the river is? It looks like Eastern Washington, which fits with the boat and the beer, but it could be SW Idaho or E. Oregon was well.
There is Crab creek, but I don't know of a section with that much water.
This is another remote river in Texas that I have heard about...The Devils River.
There should be dozens of videos about it.
Another good video. I googled the location, it does look remote.
