Jim Pumphrey, my LSU freshman roommate, was an Air Force veteran. After it looked like he was about to get drafted and sent to Vietnam, he went down to the local recruiting office to enlist in the Navy.
Turns out the Navy recruiter was out for lunch, so he walked across the hall and joined the Air Force. He said he didn’t care much which branch it was, as long as it didn’t involve jungles, snakes or rice paddies.
Pumphrey served his country honorably, then went on to teach me how to drink beer, play pinball and smoke Marlboro Reds.
