A recent Lexington County publication states: Lexington County has what it takes to make a good life. ...There's something that we think is every bit as important as sites, services and incentives. Something that's unique to our area. It's the life style. ...We're just across the river from Columbia, the state capital, so you have easy access to all of the conveniences and advantages of a major city, as well as to the academic and athletic benefits of a major university, the University of South Carolina. You see, we may be just minutes from the city, but we're miles from its hectic pace. So you get all the benefits of the city, but without sacrificing the comforts of home.
We've got nice, friendly neighborhoods here. School districts that are among the nation's best. — "The Ultimate Fringe Benefit," Lexington County Administrator Office
