Organizers of the city Halloween Carnival expect to satisfy the sweet-tooth cravings of a lot of trick-or-treaters next week, when the event will be at the Florida Suncoast Dome instead of North Shore Park. Joan Rusbridge of the city's Recreation Department said she ordered about 65,000 pieces of hard candy _ about twice what was given to children last year. Though part of the dome will be partitioned for the event, it still is cavernous enough for giant skeletons and mummies to be hung. "The crowd could be twice as big as we normally get," she said. About 5,000 attended last year's carnival. The event was moved to the dome to protect children from mosquitoes that could transmit encephalitis. People wanting to donate to the newly expanded carnival can send donations to the Halloween Fund, P.O. Box 1121, St. Petersburg 33731-1121.
