True story: I was introduced to the concepts of "win, place, and show" NOT at a horse track, but at Jai Alai at the MGM in the late '70s. My parents would go there and take me, and I would have them bet a dollar for me on a guy I guessed would win. Was fun. Kinda surprised they let kids in there, given that there was gambling allowed, but I guess it was also considered a sporting event.
