While traveling to Washington DC, I flew into Ronald Reagan Airport. Its a smaller airport but it still has a USO. The USO is probably the smallest one I ever seen. Even though it is small it still has all the essentials like food, resting chairs, and TV/Computers and very nice staff and volunteers.
