A few random thoughts about next October... (I am dreading winter and hence, I am making myself feel better by dreaming about next Spring/Summer/Fall.)
I want to make it a new tradition that I spend some time on the Colorado River during each Magical Moab Meetup. This past year, I was in a canoe (mostly!) and last year, I was on a paddle board.
I have some interest in spending time farther downstream.....
"Cataract Canyon contains 14 miles of rapids ranging in difficulty up to Class V. It is a particularly hazardous and isolated section of the Colorado River and is subject to extreme water level fluctuations." Sounds pretty gnarly, so I would want to do it with a professional river guide.
OR
I think this looks amazing. I'd have to start saving my pennies for it, though.

One other thought...when I was at Canyonlands (Needles District) a couple weeks ago, I was reminded how much I love camping there. I thought I'd make the suggestion that some meetup-ers might want to spend a couple nights there either before or after the meetup in Moab.
