An old timer in our local club was telling me a story about his first Moab Rim trip. They walked up it the day before and he said he didn't hardly sleep that night thinking about it and had himself pretty worked up by the time the run started. To top it off, a guy in front of him rolled going down Z-turn. But now it's not such a big deal anymore. I would do it again, but I'd still want a spotter in a couple spots coming down.
