Prescott to Sedona (via the mountain pass through Jerome) and up to Flagstaff, over to Williams and the Grand Canyon would be a nice ride. Going over through Jerome made me almost pxss my pants the first couple times. Long way down and some **** sharp corners.
I lived in Prescott Valley and worked at the VA in Prescott. I have a friend who drag races his own built snarly Harley, his wife drag races too. I could check with him about some good rides up through there if we have a group interested.
