Bill Horstmeyer... Died ... Bill Horstmeyer, a veteran of twelve years of racing who sucessfully raced in Badger Midgets, was entered as a rookie in his first Champ Car race in his newly purchased "big car" - the former "Central Excavating" vehicle, which he acquired from Pete Salemi. The race, a 100-mile feature event at the 1964 Illinois State Fair's one mile dirt oval, was dedicated to Tony Bettenhausen, who had been killed in practice at Indianapolis three years earlier. After having completed twenty-four laps around the track in this race Horstmeyer's car hit - or brushed - the outer wall coming out of Turn Four, dug into the dirt surfce of the course and wildly flipped end-over-end down the frontstretch. The car came to rest against a fence, trapping Horstmeyer inside his car. The Kuzma then into flames, and Horstmeyer received severe burns from which he died a few hours later in St. John's Hospital. The accident cast a dark shadow over what was otherwise a noteworthy race. A. J. Foyt won his seventh race in a row, starting from the 16th position of 18 starters, barely edging Bobby Marshman for the win. A. J. went on to win his fourth USAC National championship in five years.
