It's an annual tradition for a lot of Charlotteans, and it's happening tonight at SouthPark mall - the lighting of the mall's Christmas tree. The ceremony takes place from 5 to 9 p.m. tonight at Symphony Park. Festivities include Santa, a trackless train, carriage rides, musical guests and more. The evening will culminate with a screening of a family-friendly holiday film - Arthur Christmas. The event is free to attend and guests are welcome to bring lawn chairs and blankets.
