Time to kill at DFW
Easy question-get a car and drive to Fort Worth.
Take in a museum or two or drive through the Fort Worth Stockyards and Sundance Square and then have an early lunch. Get back to DFW in plenty of time.
Lunch suggestions:
Mexican--Joe T Garcias on the north side or The Original on the west side.
BBQ--Angelo's or Railhead
Hamburger--Kincaid's on Camp Bowie
Shoot me a PM with any questions.
Dang-I am getting hungry.
