Adrian Cronauer, the man whose military radio antics inspired a character played by Robin Williams in the film "Good Morning, Vietnam," has died. He was 79.

Fifty-two years ago a troop ship in Oakland, California sailed for Vietnam, carrying over 3,000 men.  They slept in very tight quarters on canvas hammocks – one just a few inches above the man who slept below.  That canvas was a tempting target for graffiti. Lots of it.
