Another fun thing about Oklahoma City is the Oklahoma Railway Museum. I'm not saying it is the best railway museum in the country, but it certainly the most people-friendly. Guests are invited to climb aboard any of the cars and explore the insides as well as the outsides. You'll feel like you've stepped back in time in the quiet little gift shop which is devoid of fancy marketing schemes. From time to time, you might even find Thomas the Tank Engine, who LOVES Oklahoma City!
