Yes, this trip is more than just a float down some of the best brown-water rapids in the country. It is also an opportunity for learning, not only of the rock formation and geological history, but also of water resource allocations and the unrelenting abuse of nature by humans.
We also had a group circle where we all introduced ourselves to each other. It was an opportunity led by Charly, one of the guides, for us to "merge tribes," instead of having an us-versus-them sort of dynamic. I don't know how much it helped, but at least I know everyone's names now.
