I always liked this episode a lot and especially for the Backus and Hale appearances and Alan Hale's character telling Jim West at the end about having a dream about being stranded on a desert island and the Gilligan's Island theme plays briefly, wink wink, nudge, nudge...they were filmed at the same studio on the Desilu/CBS later Paramount lot along with Gunsmoke. Gilligan's Island had a dream sequence where Gunsmoke's sets were sued, I think. Star Trek was another series filmed on the same lot and they too used elements of Gunsmoke's sets, as did Wild Wild West, most likely.
CBS/Desilu/Paramount got a lot of use out of their sound stages and indoor and outdoor sets for all the many now classic series of the 50's 60's and 70's. Believe it or not, Gunsmoke was almost 100% indoors. the main street of Dodge was a sound stage! So was Gilligan's Island. The Lagoon was outdoors next to the freeway, though. Gunsmoke eventually did location shooting though, as did Wild Wild West. Malibu State Park and the Paramount studios ranch were often used as location settings.
