First of all, Bikinis are never out of fashion in Miami. Christmas day comes around, and you can head to the beach and see your fair share of Bikinis. Second, I knew someone was going to bring up the argument of Boston, NY, and Philly. Well to be honest, the cities that sell out religiously, are either giant market cities, or small market teams with tradition (Buffalo, Green Bay, Oakland). The small teams go because there's not much to do, and the tradition is there for the teams. In NY there is a lot more things to do than in Miami, but there's also a lot more people there.
