Working for the U.S. Navy flying one of my 153 combat missions in the Vought F-8 Crusader based on the aircraft carrier USS Ticonderoga CVA-14 maneuvering off the coast of North Vietnam and having the time of my life.
I've done a lot of exciting things since then, but my personal "fun meter" has never been nearly as high as it was back then. Of course I was a youngster and perhaps I didn't know any better.
