The Lansing Historical Society will hold its gala opening of its annual Festival of Lights exhibit. More than 30 Christmas trees and displays will depict holiday celebrations from around the world and here in town. The evening will feature Christmas music by the “Wolffgang” musical group of Hobart High School. Refreshments will follow and then everyone will be invited to view the trees. Guests are invited to bring in burned out Christmas tree lights for recycling.
