Since a lot of folks have been to the area, maybe someone will know which road this is: we were driving from one base of operations to another in Utah, on a state road (I think). The road itself could have qualified as an amusement park ride. It was two lanes and narrow. Some places had huge grades (like 12%) and some areas were on the top of thin "fin" ridges where there was nothing on either side of the road (who needs guard rails?), and the scenery was amazing. It was a fairly hair-raising drive, however, and we've driven through many, many national parks, etc. This was not in a park - just driving through Utah. But I can't remember which road/route now!
