It exists at Calder also, Florida regs require pari-mutuel activity to qualify for a slot machine license. They replaced the expenses of running a horse racing meet (and cleared up tons of land they could sell) with jai-alai and they pay a few locals to put on an exhibition. I say exhibition because, although it is bettable, most games get fewer than $20 and the attendance is typically less than a local gym's pickup basketball game.
