My step-father enjoyed gambling, and there used to be Jai Alai Fronton (the court where they play) in Connecticut near Hartford and we used to go when I was a kid and he would gamble. (He wasn't a hard core gambler - more an occasional gambler.) It really kind of crazy fun to watch, because the court is likely 200 feet long and the players have these curved catching tools strapped to there hands and otherwise it's sort of like raquetball except much much bigger. There would be like 8 players or teams, and they would play like a semi round robin type thing (two players would play until one gets a point, then the loser would leave and the next player come on) and you would bet on the players/teams. I think it took about 30 minutes to play a full "game". The one in Hartford closed a while ago, so I think the only place in the USA they still play is Florida. I don't remember it being seedy, or at least any seedier than the dog track or the horse track. (In other news - I surprisingly never became a gambler even though my step-dad always did it. I think it was because I saw that you lose more than you win, and being a math whiz I just wasn't interested in something that was guaranteed to take my money.)
Now back to your regular Disney dish.
don't tell anyone lol) and that's been closed almost 10 years at this point (it had been opened for nearly 20 years total). When it was open it was quite nice though not a shopping mall. It was seen as sorta an upper thing to do. There's a push to reopen that place though. As an adult though I have to be honest that I'm not keen on it reopening not because of gambling aspect but because of who would be doing the racing (greyhounds and horses). But that's a topic for another day
