my dad has a handicapped permit due to his hip surgery-

at Cowboys stadium for the Big 12 Championship do we just get to any of the lots early and find a handicapped spot

or you still need to get a specific lot permit?

thanks

From what I remember you will need a parking pass for one of the lots then you can park in the handicap spaces in that lot.
Some of those spaces are quite a ways from where you will be entering the stadium.
You should be able to get information on the AT&T stadium website.

Having a handicap pass doesn't get you up close parking. When you enter whichever lot you park in, ask the attendant where the ADA shuttle picks up. Most lots it's right there by the entrance. They let 1 person accompany the person needing a ride. They drop off at each of the 4 corners of AT&T, and they'll pick you up there after the game. The driver who drops you should give you a card with what lot you're in, but if they don't make sure journalists know what lot you're in!
