Seriously, I don't know how Hawaii maintains any sort of a pool community. I was there for two weeks last month and not only is there very little pool (none in Maui), there's almost no desire to be indoors or out at night. I'm sure it's different on O'ahu but can't imagine it's anything like New York.
Gambling in Hawaii is strictly prohibited, so gamblers have to go to the pool hall to get any action.
