Every spring and fall thousands of people come to the racetrack to socialize, gamble, and enjoy the horse races that have become so popular in Kentucky.

The study investigates which factors significantly contribute to attendance by Keeneland visitors. (Source: Data from Gatton School of Business and Economics publication, Gatton College, 2009.)
