When we decided to drive historic Route 66 from Chicago to Los Angeles, we envisioned the journey as another way to explore the American West. Our earlier trips had followed the route of Lewis and Clark or had used the National Parks as a theme. But until we walked down Santa Monica Pier, 2,828 miles and ten days after we left Chicago, I had not realized that traveling the Mother Road of 50 years ago would offer a nostalgic lesson in the automobile travel that our parents and grandparents had experienced. Winding our way along the remaining patches of the old route, we were following the road that Americans drove before the Interstate Highway System changed automobile travel forever.
