DARLINGTON - The 1940s is when Jackie Robinson became the first African-American major league baseball player and World War II was in full swing. It is also when the Lafayette County Speedway got its start. "I think there has been a strong racing heritage between Darlington and the Freeport area," said Jason Udelhofen, the director of the Lafayette County Speedway which has catered to drivers for more than a half a century.
