I found one while Scuba diving off Hawaii years ago. it said "Royal Order Of The Purple Dorks" and "Roark" with a number. Some sort of unofficial military social club?
I was in basic training in Ft. Ord Ca. Not even done with training we were placed on alert. Rifles and bayonets but no ammo yet. When Kennedy was killed I was in the 101st abn and we got all our war stuff but nothing happened. Interesting times.
