Steve - Thanks for posting the Ark video. It is Three Rocks and Sunshine rapids. That was crazy high water this year, 6000 cfs. It was so fast we were able to do a few runs each day we were there. Very exciting.
The video showed the difference between having a paddle crew vs. a single rower. In Three Rocks it looked like some of the paddle crews were not able to get their boats over to where they needed to be, far right or far left. The oar boats we had, and others we saw, were able to.
I've always been amazed that the guides take all kinds of crews downriver, some competent and, I would guess, many not, such that a guide would have to be thinking, "What the f*ck is going to happen today?"
