We’re getting old, you guys. OKC is about to turn 125, but we still know how to party (with birthday cake, obviously). Locals can attend an open house 9 a.m.-4 p.m. Tuesday at City Hall, 200 N. Walker Ave., featuring history lessons, a Spokies bike history tour, tours of City Hall and, yes, birthday cake. Admission is free. Call 297-2578 or visit okc.gov. See our 125th Anniversary weekly series story on page 28. Also, check out our Spokies story on page 43.
