Texas as a whole took the recession a whole lot better than most states, but when your town's main strengths are technology and energy and its most well-heeled tenants include AT&T ( T), Texas Instruments ( TXN), Southwest Airlines ( LUV), Tenet Healthcare ( THC), Celanese ( CE) and Atmos Energy ( ATO), you've got a city built for survival. Forget about a real estate bust also, as the larger Dallas-Fort Worth metro area has grown 25% since 2000 -- making it the fastest-growing major city in the U.S. Judging by the nearly 57 million people that came through Dallas-Fort Worth Airport last year, making it the fourth-busiest in the U.S. behind Atlanta, Chicago O'Hare and Los Angeles, more are on the way.
