Gary Army Airfield
Organized San Marcans fought to save the base, and on November 20, 1964, President Lyndon B. Johnson announced in a speech at his alma mater, Southwest Texas State University, that the abandoned Camp Gary would be the site of a new federal vocational training facility called Job Corps. Today it's known as the Gary Job Corps Center, the largest in the nation.
