In his book, South Dakota's Challenges Since 1960, Charles Rogers explores nearly a half-century of South Dakota’s most recent history. Rogers taught American history at Scotland High School, Washington High School and Kilian Community College in Sioux Falls. His book focuses on energy development, population, well-known South Dakotans, and the state’s economic ups and downs. He’s giving a presentation about the book on Tuesday, February 3 at the History Club of Sioux Falls.
