Just an explanation of what "Bypass 66" meant. Back when 66 went through every major city on its way to California, there was a way around the city called "Bypass 66." Here in St. Louis, the 66 enthusists claim the highway went over the "Chain of Rock Bridge." No it didn't, the "By Pass 66" went over the bridge, 66 went through St. Louis and St. Louis County on its way to Springfield, Missouri. The enthusists only use the bridge as a focal point because it is still there, they don't explain how travelers got to the bridge and where they went after they got off the bridge.
Again here in St. Louis County, there is a great deal of history (Motels, etc.) on old "By Pass 66" that is being overlook. Many of them are still there, by nobody pays any attention to them.
I can only guess at your question, and I would say it was probably from around the Springfield, Missouri area.
