Join the USO in celebrating a safe return to its legacy in-person entertainment tours! A special summer performance featuring a variety of entertainers will take place July 1 from 7:30 to 9 p.m. at the Joint Base San Antonio-Lackland Amphitheater. The talent line-up will also participate in several activities on-base prior to their performance. The USO Summer Tour is free and open to active duty, dependent and Department of Defense ID cardholders. Due to limited seating, attendees are asked to bring lawn chairs and blankets.
