River Surfing In Idaho Is A Thing

I stumbled across a video of an activity that I did not know was a thing here in Idaho. It features a guy river surfing. Yes, surfing in Idaho is indeed a thing.

I figured it might be one guy who thought it would be fun, but no, it's apparently a movement, especially near Boise.

The surfing isn't limited to boards as there are some kayak dudes that managed this on the Lochsa River in northern Idaho.

Have you ever attempted this on any of our many rivers? If you have video and/or photographic evidence, please share.
