FILE - In this May 3, 2014, file photo, fans watch a race on a large video screen before the Kentucky Derby horse race at Churchill Downs in Louisville, Ky. A racehorse died Thursday, May 22, 2014, at Churchill Downs after a freak fall that the trainer blamed on the sound of a starting gate bell blaring on the track's new sound system. The 5-year-old mare Never Tell Lynda was walking toward the paddock on the dirt track when she reared, twisted and fell, hitting her head, said her trainer, Kenneth Wirth. Wirth later said the horse was spooked by what Wirth thinks was the sound of a starting gate bell coming from a commercial on Churchill's massive new video board. The system includes 750 speakers.
