I was looking at some of the older UA routes. They alternated road days and trail days. Some of the road days were 300mi or more. That makes John's idea about Harlan ->Hatfield -> Rausch viable.
Golden Mountain is fun, but it's sort of like a great big version of the Flats. Ride over here, do this obstacle, ride over there, do that one, run back to camp for a snack, etc. Very different than Harlan or Windrock, where you can get very lost.
