OKC: This 55-foot tall "Eleanor Blake Kirkpatrick Memorial Tower" is Chihuly's tallest glass sculpture. I didn't know the Oklahoma City Museum of Art had one of the largest collections of Chihuly glass in the world! Very impressed with paintings as well, which recently were changed to combine abstract with representational in the same room.
Past and present fuse in Oklahoma City, where you’ll find the legacies of Native Americans, cowboys and cattle. Things to do include visiting the National Cowboy and Western Heritage Museum, the Oklahoma Museum of Art and the Oklahoma City National Memorial and Museum: http://www.midwestliving.com/travel/around-the-region/oklahoma-city-trip-guide
