Not a particularly great show, but it launched the career of Clint Eastwood, and had what is arguably the most recognizable and famous theme song any TV series ever had.

I loved this series and watched it whenever I could. Ridge, they were usually driving cattle from Texas to Sedalia, Missouri, as I recollect. Then they would go back to Texas and start over. The series was cancelled in 1965 in the midst of a drive when Clint Eastwood took over as trail boss. As far as I know those cattle are still out there, wandering around.
