NB...no hard feelings towards Memphis and it's airport...but know this...I've lived in both Memphis and Nashville, and I've found that it's hard to have a conversation with a Memphian when the topic of Nashville comes up. Seems that our brothers in Memphis either see us as competition or just outright hate Nashvillians.
By the way...your comment about our "automobile plants", as if that's all we have, is misguided. The Nashville area DOES have 2 automobile plants that employ more than 10,000 people...we're one of the largest book publishing headquarters in the world...we're one of the top 3 music headquarters in the world...one of the largest healthcare centers in the US...and we're about to have the tallest skyscraper outside of New York and Chicago.
Oh...and we're the largest metropolitan area in Tennessee.
