My dad joined the US Army and volunteered for active duty during the Korean Conflict. Instead, he was sent to Germany. He was in the Quartermaster Corps.
The way he tells it, they were always being asked to volunteer. “Who knows how to drive a truck?” Everyone would raise his hand, then be sent to dig ditches. “Who knows how to shovel out a barn?” Of course no one but Dad raised his hand, and Dad was sent off on fun adventures. He learned to volunteer for everything because the great stuff he got to do far outweighed the ditch-digging moments.
His optimism and sense of adventure served him well.
