If you ever want to see Bob Denver in a western he did one with Forest Tucker {Sarge on F-Troop}The Wackiest Wagon Train in the West. He pretty much continued the Gilligan character in it. LOL.
That was sort of an ersatz film culled from the “Dusty’s Trail” series, which was pretty obviously patterned after “Gilligan.” Apparently, “Gilligan” was doing gangbusters in rerun syndication in the early-70s, so to capitalize on that, “Dusty’s Trail” was produced and sold as a non-network, made-for-syndication series. Really low budget. Only lasted a single season, but I remember one of our local stations airing it on Saturday afternoons, around 1973.
