The Oklahoma City Zoo will host Sales Tax Appreciation Day today, with guests getting free admission. This year marks the 29th anniversary of the eighth of a cent dedicated sales tax being passed by Oklahoma City residents for the Oklahoma City Zoo and Botanical Garden.

Passed by Oklahoma City citizens in 1990, the sales tax has made numerous capital improvements possible at the zoo, including Great EscApe, Cat Forest/Lion Overlook, Oklahoma Trails, the Children’s Zoo, the Elephant Habitat, the Joan Kirkpatrick Animal Hospital and the new Sanctuary Asia habitat.

This summer, the zoo amphitheatre concerts will be:

• Today — Young The Giant + Fitz & the Tantrums

• July 28 — Alice Cooper/Halestorm

• Aug. — Bush/Live

• Aug. 23 — Casey Donahew

The zoo amphitheatre is adjacent to the Oklahoma City Zoo. For more information, visit thezooamphitheatre.com.
