“The W.R.S.A. is committed to the exploration of stationary waves while promoting and expanding the sport of river surfing. These waves will open up the entire world to surfing. At this point little is known about how many of these waves exist. Look at a map. Anywhere there is a current of water, the possibility for the formation of a stationary wave exists.”
