DFW Airport is brilliantly simple to navigate. You have to have blonde brain matter in order to get lost or screwed up.
If you know the first five letters of the alphabet in order, and if you know the meaning of 'arrival' and 'departure', and if you know the difference between south and north, and if you can drive on a wide modern freeway, and if you can handle left-hand exits, then you have all the lifskills and mental tools you'll need.
