I wouldn't bother. We added this stop to our road trip because my daughter loves dinosaurs. With the name, "T Rex Natural History Museum" you'd think that it was a decent sized museum with lots of info about T Rex and other dinosaurs, WRONG. It is a very tiny building with more rocks than actual dinosaurs. The picture on Roadtrippers makes it seem like there is a full T Rex skeleton but in reality, it is a cast of the T Rex "Sue" head along with another cast of a Triceratops and that's about it.
Nothing interesting at all about this place. Seems like they have the T Rex cast just so they can suck people in to coming here to sell them rocks. Admission was only $1, anything more I would have asked for a refund.
If I could give negative stars I would. We went out of our way to come here and it was a big waste of time.
