It was awesome. Had some very respectable rapids (quartzsite, black rock, pinball, etc) some of which people chose to portage around, and people got dumped. We had to use throw ropes, etc.
One of our leaders was an actual licensed River guide and had all the gear we needed. He did it all for free, but because we gave him money to go buy the food at costco, he was somehow prosecuted for "guiding" this trip as a professional without the right permit or some crap. Crappy result from an amazing trip.
