We have a good friend that lives in the area so transportation was not an issue, but renting a car would be a good way to go also. Looking forward to going back so we can go the the Cowboy museum.
I haven't been in years, but the Cowboy Hall of Fame (actually called
National Cowboy & Western Heritage Museum ) is a
really cool and interesting place. 18 acres all together, just a wonderful collection of western history, art, and memorabilia on the American West.
If you ever have occasion to go down US 81 from OKC through Duncan OK, just about 80 mi (I often go that way to Dallas instead of I-35), there's an equally cool, though much smaller, museum on the Chisholm Trail, cattle drives, and the ways of the west:
Chisholm Trail Heritage Center
It's a multi-sensory experience, meaning when you're watching the film about the history of the Chisholm Trail, the floor shakes and rumbles during stampedes, it rains mist from the ceiling, etc and you get much more of a feel for things. I've been to a slew of museums around the country and highly recommend this one.
Not far from Duncan (which was also the home of
Erle P Halliburton, and now offices for Halliburton Co) is Ft Sill, in Lawton OK, which has the very cool
Fort Sill National Historic Landmark Museum.
There's also a cool Cowgirl Museum in Ft Worth, if down in the Metroplex and wandering around on a layover:
