My wife, who is kind of squeamish, wants to go to Moab next spring but I'm not sure she will appreciate some of the trails, like Hells Revenge, or the 7 mile Rim Trail. How off camber is the section of 7 Mile Rim, that's what freaks her out the most. How does the R&T handle the escalator in Hells Revenge? Any recommendations on rides not too scary for her? Oh yeah, someone told me if it's your first time there it is a good idea to hire a guide to assist on some of the trickier sections...is that a good idea? thanks
