How far West are you planning to go. We have traveled
US-60 from Wickenburg, AZ through NM and into Texas. Lots of small towns and wide open spaces. It goes through the White Mountains in the Apache-Sitgreaves National Forest and the Cibola National Forest. A lot of two lane, usually in good condition when we were last there a couple of years ago.
We have also been on portions in the Daniel Boone National Forest in KY near Salt Lick and Cave Run Lake.
