At its peak during WWII, Mare Island Naval Shipyard employed over 40,000 "Yardbirds" – the term used to refer to civilian welders, shipbuilders, pipefitters, and other tradesmen that worked on the island. Many a Yardbird from the old days have told us of their penchant for a liquid lunch. Or, as they affectionally have referred to it, hoisting a "hydraulic sandwich".
