Camp Adair's post exchanges (PXs) came in two different sizes, with the largest measuring approximately 50 by 150 feet. These stores were much more than places to shop—they served as important gathering places where soldiers could relax and purchase everyday necessities.
Many of the larger PXs included barber shops, soda fountains, and lunch counters where soldiers could buy food, soft drinks, and alcoholic beverages when permitted. The stores stocked a wide variety of merchandise, including toothpaste, toothbrushes, combs, shaving supplies, clothing items, and other daily essentials. They also sold bicycles and souvenirs that soldiers could purchase or send home to loved ones, including decorative pillow covers that could be mailed like postcards.
Most of the PXs were staffed by local civilian employees, many of whom were young women from the surrounding communities. These employees played an important role in keeping the post exchanges operating smoothly and providing friendly service to the thousands of soldiers stationed at Camp Adair.
