For the record, I got taken to Golden on Friday for a lesson, it was my 9th time in a boat, and 3rd on moving water. We ran the section twice, I swam 3 times (held out for one t-rescue - yay me!) and my paddle wanted to go have a beer one time. If my instructor was a little over-ambitious about my skills, he at least did all that paddling after my own paddle.
It did scare the crap out of me - triggered a real adrenaline rush that was very unhelpful. But I kind of made the best of it, and now I'm headed back to C470 for more confidence building.
And hey, I did get some real practice swimming among rocks and getting out of the current.
I think those eddies are really tractor beams
