Far and Wide

Coming back from Newark, Ohio, the home of the famous Ohio Cosgriffs, I was forced into a detour because of road work. Man proposes; such is life.

The rerouting took me quite a bit farther into the Buckeye countryside than I expected. While tooling north on Sate Route 37 I happened to notice that the farmlands whipping by me were going at a certain speed which matched the pace of the opening credits on an old TV show. Indeed I commenced to humming and singing the little ditty as I drove along.

Your challenge today, reader, is: what show am I talking about?

It's probably too easy, but, hey.
