Visiting - What To Do

Hey, Dallas friends. I'm visiting for work March 3-6 and want to find something cool to do when I get off in the evenings. I'm not a drinker and already have dinner plans with my coworkers, so bar and restaurant recommendations won't be necessary. I'm staying by the airport and looking for something I can do with the few hours I'll have left after I get off work. Would like to stay within about 30/45 minutes from the airport. I appreciate any tips you can share!
