An Air Force nurse from Georgia during the Vietnam War era, Judith Crosby survived an interrogation and investigation into her sexuality at the same time she was coming to oppose the American war in Vietnam. (Photo courtesy of Judith Crosby.)
Judith Crosby began questioning her sexuality during nursing school, but she knew that homosexuality was considered “abnormal” and “deviant” behavior. Not wanting to be branded as such, she partied, had sex with men, and tried to bury her feelings for women.
Check out the interview of Judith completed for the Veteran’s History Project: Interview with Judith Crosby (2/3/2004).

They consisted basically of repair and maintenance shops, floating dry docks, pontoon piers, crane pads, POL storage, utilities, and roads. This is the Market Time site at Cam Ranh Bay.
As naval facilities, all six installations were built by US Navy Seabees.
