From here to there.
Our basic route from Ann Arbor, Michigan to Los Angeles, California last week.
Hard to tell on this map, but a lot of it between Colorado and California was on two-lane back roads with side trips to see the scenes. That included a section of the original Route 66 in western Arizona that passes through Oatman. About 65 miles of excellent-for-Mustang GT-spirited-driving connected Oatman to the two ends between highways.
