Wow, I really started something good here. Gotta love it indeed !
My Cuban Missile Crisis story. My dad was on his way back from Germany in a troop ship when it happened, due to be discharged from the Army on his return to the States. He had been in Berlin when the Wall was knee high, exchanging jokes and insults with the East Germans.
His ship was diverted to Cuba. But the thing was resolved by the time it got within 100 miles of it.
