I've had mine for a while (right, guys?).. and since it was given in fun and affection, I treasure it!
At the stop at Emsworth locks going into Pittsburgh, one of the young Coast Guard officers sent one of the crew over to see if I would talk to him for a moment (he couldn't leave his station). He wanted to know if I knew what "that" meant.. and he received a great surprise and lots of laughter!
And no, I didn't try any of your newbie tricks on him. I thought he probably had heard them all - unlike this poor innocent daughter of a WWII veteran!
