While schools are closed, we're creating a series of "Talk of Iowa" episodes that will be fun and educational for learners of all ages. Every Tuesday, we'll learn about Iowa wildlife, and every Thursday, we'll learn about Iowa history. Our series continues with a look at the history of the good roads movement and the Lincoln Highway in Iowa. The guides for this hour of history will be Tom Morain of Graceland University and former director of the State Historical Society of Iowa and Drake Hokanson, author of The Lincoln Highway: Main Street Across America .
