Tunica is a town in Tunica County, Mississippi, near the Mississippi River. Until the early 1990s the town was one of the most impoverished places in the United States, semi-famous for the particularly deprived neighborhood known as Sugar Ditch Alley, named for the open sewer located there.
Today, Tunica County is the third largest gaming market in the nation with 9 world-class casinos featuring 24-hour gaming plus all the amenities of modern full-service vacation resorts.
