There are local ones in big cities but there is a giant annual one in Vegas. One year there was a full scale recreation of Quark's bar, it's a pretty big production usually. I'd love to go to one and if I ever have money and vacation time that'd be my first pick. I mean, I'd also go look at a desert and try to see a grand canyon since I'm over that way too, as well as other Vegas shit, but it'd be the reason for being there.
