<P> Like Rogers's and many other Western films of the 1930s through 1950s, the series featured traditional cowboys and cowgirls riding horses and carrying six - shooters in a contemporary setting where they coexisted with automobiles, telephones, and electric lighting . No attempt was made in the scripts to explain or justify this strange amalgamation of 19th - century characters with 20th - century technology . Typical episodes followed the stars as they rescued the weak and helpless from the clutches of dishonest lawmen, con artists, bank robbers, claim jumpers, rustlers, and other "bad guys ." </P> <P> In addition to traditional Western plot themes such as cattle rustling and bank robberies, the program featured more contemporary topics, including gun safety and conservation of natural resources . "Many of the shows expressed a moral, and several preached a Christian message ." </P> <P> Interior shots for the show were filmed at the Samuel Goldwyn Studio, with much of the outdoor action footage filmed on the Iverson Movie Ranch in Chatsworth, Los Angeles, California The program was originally sponsored by General Foods (Post Cereals and Jell - O). The show's theme song, "Happy Trails", was written by Dale Evans and sung by her and Rogers over the end credits of each episode . </P> <P> The show received an Emmy nomination in 1955 for Best Western or Adventure Series, but it lost out to the syndicated Stories of the Century, an anthology series starring and narrated by Jim Davis . The series finished #27 in the Nielsen ratings for the 1951 - 1952 season and #30 for 1954 - 1955 . </P>
