Getting together for cocoa and Christmas caroling isn’t safe during this pandemic. But people can still hop in their cars to see drive-thru light displays. Irwindale Speedway and Dodger Stadium offer big professional light installations. Small communities around Southern California are also going all out. Plus, what’s this time of year without “The Nutcracker?” The Los Angeles Ballet is hosting an interactive digital tea party, where people can meet Clara and hum along to the “March of the Toy Soldiers.”
