We were on the USS Okinawa LPH3 in 69 along with 2/26 (I think) floating up and down from the DMZ to Chu Li looking for trouble. We were using the old UH 34Ds to transport the grunts. After flight quarters were secured and after dark abuddy and myself would go up on the flight deck and swing our legs off the rear of the deck,sit and solve all the worlds problems. Right under us was fan tail and after dark the “dobbie” brothers would congregate there and do a few “Dr Feelgoods” and converse on an intellectual level. Now there was a door to enter/exit so EVERY time the door opened why a person had never seen so many fireflys flying off the fantail.The aroma would float up to us to the point we had to move (second hand “doobie”) …..Skip and I would laugh seeing all that good weed flying away and the cost. Full disclosure: Never smoked it period!…My drug of choise was alcohol.
