New Yorker visiting Oklahoma City area for the next couple of weeks. What should I not miss?

My sister recently moved to the OKC area (Weatherford, about an hour out) and I will be visiting her for the next few weeks. I just want to know what in this area should I not miss. OKC bars, restaurants, cool sites in the surrounding areas, anyplace at all that if your friends were in town you would take them.

Also if any redditors want to hang out on the weekends or even weekdays I'd love to meet and share a drink with you guys and gals.

Thank you.
