In this July 26, 2011 photo, Please Boundary, right, with jockey Uriel Lopez up charges down the homestretch during a race at Fairmount Park near Collinsville, Ill., just east of St. Louis. During a summer swelter that prompted horse tracks elsewhere to cancel their race cards on certain days, Fairmount races pressed on as operators put faith in procedures put in place to minimize the exposure to the heat by the jockeys and horses.
