Usually when people scare you for money it's called a hold-up. In October, it's known as Halloween. From Netherworld's evil clown-inhabited slaughterhouse to the spooky 10,000-square-foot voodoo swamp at Creepers, HAUNTED HOUSES can really bring the terror. There's also ScreamWorks, a four-in-one deal that includes the Slammer, a maximum-security prison with a Lord of the Flies philosophy. Through OCT. 31. Creepers: $15-$30.
