There's a whole series from this rapids area for 2 riders. I told them where to find their shots, who knows if they'll remember after riding. Well, I had fun doing the shoot anyway... I really got lucky on the section I viewed from overhead. I saw them and got a glimpse and motored ahead to setup, so I Was expecting them when they arrived. here are the rest of the series: http://fotogafer.smugmug.com/gallery/2680725#141926267 maybe I should have zoomed a bit tighter. But I had little setup time, I just had to go with it.
