Certain cities are known for certain things, and it's sort of part of their identity.  Like Las Vegas's business is gambling, Los Angeles's is movies and TV, and Detroit's (at one point) was cars.  I went to Nashville recently, and their business is country music.  The city I live in now is Huntsville, AL and our business is rockets.  For Tuscaloosa, a city I recently visited which is home to the University of Alabama, their business can best be described as "football team." #business
