Over 100 volunteers enjoyed the ribbon-cutting at the new state-of-the-art U.S.O. Neil Ash Airport Center at the San Diego International Airport. City officials, the business community and military personnel were on hand to celebrate the opening of the largest U.S.O. airport center in the world. Attendees got a first-hand tour of the facilities that provide support to over 125,000 troops and their families annually with the help of the more than 22,000 volunteer hours.
