You Absolutely Must ______ While Visiting Abilene! Fill in the Blank

I have a lot of family and friends who are planning to visit Abilene for the first time. Of course, they’re coming to visit our new baby and the rest of the family, but I want to make sure they get a chance to enjoy some of the Abilene culture.

Abilene has a cool zoo, museum, Frontier Texas, great dining, a drive-in movie theater, and several other attractions that make our city unique. I think anybody visiting for a few days would have no problem keeping busy.

But if you suggested something to see or do in Abilene to someone from out of town, what would it be? What is it that makes your suggestion an “absolute must” see or do?
