If viewing this exhibition every holiday season isn’t part of your family’s repertoire yet, well, there’s not too much hope that a parent-of-the-year nomination will come your way anytime soon. But you can change that by starting a new tradition this year. First of all, the Trains at NorthPark is set up at NorthPark Center, where we know you spend plenty of time. Secondly, the trains are just cool. The exhibit features mini versions of Mount Rushmore, Times Square, and even the Dallas skyline. There are more than 2,800 square feet of track and dozens of vintage trains. Lastly, proceeds benefit the Ronald McDonald House of Dallas. We can see your kiddos smiling now. Nov 21–Jan 3. NorthPark Center, 8687 N. Central Expwy. 214-631-7354. www.rmhdallas.com.
