Do your kids have letters to Santa they are dying to send? Let them put their missives in Santa’s Special Mailbox. You’ll find it at the free 17th Annual Windsor Holiday Celebration on December 7, 5–8 p.m., at the Town Green in Windsor. Kids can get their pictures shot with Santa, too, as well as take rides in a horse-drawn carriage or stroll through the Charlie Brown Christmas Tree Grove. The town tree will be lit at 7 p.m. Find the full schedule of events at townofwindsor.com/347/Holiday-Celebration.
