Santa's mailbox in Cary is officially open for the holiday season. The bright red mailbox can be found in Downtown Cary Park — all decked out for the holidays. The Town of Cary expects to process more than a thousand letters to Santa this year from near and far. Cary’s Santa’s Mailbox is open until December 24. Joy Ennis, General Manager for the Downtown Cary Park, joined Jeff Hamlin to discuss Santa’s Mailbox.
