You know who else was a staple guest star on those shows, MP? Tom Skerritt.

Most people remember him as the sheriff on "Picket Fences," or as Mr. Drake on "Cheers." But back in the '60s he had to be in a dozen or so episodes of "Gunsmoke" and "Bonanza."

Good character actor. He had that rugged, outdoor look. A natural for a cowboy .
