Ranger Bill, Warrior of the Woodland, struggling against extreme odds, traveling dangerous trails, fighting the many enemies of nature. This is the job of the guardian of the forest, Ranger Bill. Pouring rain, freezing cold, blistering heat, snows, floods, bears, rattlesnakes, mountain lions. Yes, all this in exchange for the satisfaction and pride of a job well done.” That was the opening of Ranger Bill, a Christian radio adventure serial produced under the auspices of the Moody Broadcasting Network and the Moody Bible Institute. There were 206 episodes of Ranger Bill, which ran from 1950 to 1954 in a 15-minute format on WMBI in Chicago, and in syndication as a 30-minute show from 1954 to 1962.
