Ready to usher in the holiday season? Well, so is the rest of the Chicago, and we can all kick it off together at this year’s Magnificent Mile Lights Festival. This Saturday at 5:30, the millions of dazzling Christmas lights will sparkle to life up and down Michigan Avenue. Holiday fun will be happening all weekend, from 11am-10pm, including live performances by Justin Roberts, Mitchell Musso, and Plain White T’s. The kids can even meet Mickey Mouse, who will be leading the parade down Michigan Avenue. Those of you looking to shop, rejoice! Retail stores along the Mag Mile will be holding extended hours all weekend for the festivities.
