I just came down US-85 to Torrington on Friday. It is only 10 miles or so west of -159. Done -85 many times and never considered -159. Have my GPS set to avoid unpaved roads, and I think I’ll keep that setting. Glad you were able to get turned around safely. So many farm/ranch roads in the western states are dirt. Some are ok, but I find it best to generally to avoid them.
