This Western anthology moseyed along quietly for almost half a century (22 years on radio), and was set in Death Valley, Cal., because that's where its sponsor's product, 20 Mule Team Borax, was mined. Characters were always more important than action, and the most recognizable was the host. For 13 seasons it was `Old Ranger' Stanley Andrews. Then came Ronald Reagan, who left after one season. His next job: governor of California.
