Next Thursday’s free and open-to-the-public forum at the National Sprint Car Museum is entitled “Sprint Car 101: An Evening with Iowa racing historian Bill Haglund.” The program will start at 7 p.m. on the museum’s second floor. The first hour will focus on Bill’s life, his career in racing, and his new book, “Racing Through Time: A History of Automobile Racing in Iowa.” The second hour will feature a book-selling and book-signing opportunity for racing fans in south central Iowa.
