The Michigan International Speedway is located in Brooklyn, Michigan. The race track opened in 1968 with a seating capacity of 25,000, a figure that was considerably increased after racer and entrepreneur Roger Penske bought the speedway in 1972 and upgraded it. Known as the Michigan Speedway between 1996 and 2000, the track later reverted to its original name. It primarily holds NASCAR races such as the Firekeepers Casino 400 and Consumers Energy 400 among other NASCAR-related racing series events. NASCAR drivers who competed at the Michigan International Speedway include Bobby Allison, Mario Andretti, Buddy Baker, Dale Earnhardt, Jeff Gordon, Richard Petty, and Cale Yarborough.
