Mail to the North Pole from Greencastle is piling up. Local workers are rushing to deliver letters as quickly as they come in. All letters for Santa may be dropped off at Santa's mailbox, located on the ELM side of the square through this weekend. According to Georgina Cranston, executive director of the Greencastle Chamber of Commerce, Santa will reply to letters received by Monday, since things get pretty busy at the North Pole later next week. "I have Santa's ear," Cranston said. "Get your letters to Santa in by Monday and he said he will answer your letters." Santa's mailbox is sponsored by Peak Performance and Corning Credit Union.
