I only see one store in Fort Worth Texas: http://www.apple.com/retail/universityparkvillage/
One thing I'll mention incase you don't know, you can make a reservation online here: http://www.apple.com/retail/geniusbar/ If you don't make a reservation, they will put you in a standby line and you might have to wait awhile.
Also, I don't think you'll have to worry, the customer service at Apple pretty good.
