America’s Semiquincentennial at Steam Pump Ranch
The Oro Valley Historical Society is proud to continue celebrating America’s Semiquincentennial—our nation’s 250th anniversary. It’s a big word for an even bigger milestone. Join us each Saturday through February 14 at the Pusch House Museum at historic Steam Pump Ranch from 9 a.m. to noon. Explore how our country came into being, the people who shaped it, and the actions that secured the freedoms we enjoy today. Volunteers will be available to share insights and answer questions. As always, self-guided tours are free, with donations gratefully accepted.
