I was binge watching the old Route 66 TV show on Roku today, and was surprised to see DPD motorcycle officer Bobby Hargis portraying a Dallas Police Officer in a show set in Dallas from episode 19 of the second season, originally shown on February 16, 1962. The episode was called "Aren't You Surprised to See Me?" The officer looked familiar to me, so I checked the credits after the show and sure enough. He only appeared briefly, but there he was. Also some scenes shot at Love field and other Dallas locations.
I just found out Mr. Hargis passed away April 14, 2021, about 6 weeks ago. RIP
