PETA can chill, because at no time during Saturday’s Bowling for Rhinos will anyone actually hurl a bowling ball at a rhino. That’s because they can’t fit through the doors of AMF Boulevard Lanes, 3501 S. Boulevard in Edmond. If you can, the Oklahoma City Zoo invites you to its 18th annual event to benefit rhino conservation. Admission is $25. Call 424-3344 or visit okczoo.com.
