Stand up and River surfing are super fun.  On the river, the wave never dissipates!!!  This is a picture of Carrington barrs paddling into Colorado Wave on the Lower Deschutes River in Oregon.  Carrington and Gabe are awesome surfers with lots of experience in Mexico, and Indo- but I think this was there first time surfing a standing river wave.   This was on the second day of the lower Deschutes river wilderness trip.
