This is only a suggestion, only because it would involve being a full day or a two day Z cruise. Last weekend I had to fly some passenger to the Western Slope and noticed some highways having some huge potential. Maybe meeting in Gunnison and then proceeding to the HWY 50-92 junction. From Sapinero on HWY 92 Westbound for 20 miles there appeared to be over 90 turns on that road. In the pictures you can see the elevation change and it runs right along the canyon. From the air it looked spectacular.
