America's newest ``Hot Doughnuts Now'' sign will be lit at 5:30 a.m. Tuesday, Dec. 19, as Krispy Kreme Doughnuts, Inc. (Nasdaq: KREM) arrive in Citrus Heights, bringing a young city with a bright future a sweet Southern treat. Located across from Sunrise Mall on the corner of Greenback Lane and Sunrise Boulevard, the Citrus Heights store is the second Krispy Kreme in California's capital region and the fourth in Northern California. But for thousands of holiday shoppers, the store will be the first place to find hot and fresh doughnuts.
