T.O.
I 2nd Babes but I would go to the Roanoke location. More country looking. If you go on Friday or Saturday night you'll be waiting forever if you don't go early... like 5 or 5:30.
All the ideas give have been great, but don't forget the JFK Museum and the Ft. Worth Stockyards, and Grapevine. You can ride the Tarantula Train from Grapevine to the Ft. Worth Stockyards.
