my dad did his time at MCRD Parris Island
We went back there this summer to visit the place because I wanted to see the Island. When we got to the main visitors gate, the guard asked to see some kind of ID. my dad gave him his old USMC ID card, from the Vietnam era. The writing is kinda blurry, and the MP barks, "COLONEL Lewis", proceed.
My dad was a corporal.
my dad has never laughed harder, or felt more flattered since.
