One unusual thing about camping in remote areas is that there is an excessive amount of discussion about bodily functions -- when to go, where to go, how long you can avoid going, etc.
Much as I'd like to take in these sights and even knowing how much fun Tonya had, I can't see going camping. And camping with boating seems even worse, because you've got all that sun exposure. But that's just me. I love the Western landscapes. Taking them in, however, I have some strong preferences. Transportation: car. Where to sleep: hotel. Place to tend to physical needs: women-only bathroom.
UPDATE: I will note that I would be willing to go on the kind of rafting trip Tonya describes if I were paid enough. Putting a price on things like this is an Althouse tradition. I'm assuming a week-long raft trip, well-run, well-supplied, with people I enjoyed and through a landscape I wanted to see. I would do it for $1,000 -- the equivalent of "Star Wars" and an egg salad sandwich in Althouse valuation.
