TULSA, Okla. — Oklahoma has always had a troubled relationship with her native son Woody Guthrie. The communist sympathies of America’s balladeer infuriated local detractors. In 1999 a wealthy donor’s objections forced the Cowboy Museum in Oklahoma City to cancel a planned exhibition on Guthrie organized by the Smithsonian Institution. It wasn’t until 2006, nearly four decades after his death, that the Oklahoma Hall of Fame got around to adding him to its ranks.
