Book excerpt: For most Americans, Iowa brings to mind endless acres of corn fields, one of the country’s longest-running state fairs, and American Gothic, but few may know how it serendipitously became the birthplace of the most iconic apple, why thousands of cyclists brave the Midwestern heat and humidity to cross the entire state one week each year, or how a former Des Moines sports announcer became one of the White House’s most popular residents. It Happened in Iowa goes behind the scenes to tell these stories and many more, in short episodes that reveal the intriguing people and events that have shaped the Hawkeye State.
