Haven't been whitewater rafting in quite some time, so took the opportunity to take a newbie to experience it. Late summer flow on the South Fork of the American River. I went with Whitewater Voyages, through which I went on the Middle Fork for my 1st trip). We had a cool guide, Sam, and 3 other strong guys to make a boat of 5 + Sam. Apparantly, we got lucky, in that the day before, they had run 20 boats, whereas this day, there was only us, and another boat being run by another guide for her family. This was especially lucky because they're not allowed to run a single boat. With the rapids fairly mellow, we ran all of them through the gnarliest parts of them, getting stuck a couple of times, and wet lots of times. I actually got bumped out on the 1st set of rapids and had to swim back to the boat. It was a bit cold until I dried off. Later in the run, after lunch, it was warmer without the wind of the 1st part. We did some tricks that I hadn't seen done before, for example...
