Away from the betting lines and exclusive club rooms of Churchill Downs is another world: the backside of the track, where hot walkers, grooms, exercise riders and jockeys rule. This is what the Louisville Story Program chose for its latest project, “Better Lucky Than Good.” The Story Program, started in 2013, recounts the history of local places and events by recruiting people in the chosen community to write about their experiences. This is the first time that equine workers in American Thoroughbred racing have documented their jobs for the public, organizers say, and the Story Program spent three years engaging them, as well as residents of South Louisville. At this book launch event, meet and celebrate the more than 30 authors, who will be signing copies. —Danielle Grady
