Last year P made me watch the movie Battleship. It was really bad. But the ships in it were cool and today we went aboard one that was in that movie; USS Missouri. We booked the tour that takes you all the way in and down - the boiler room, gun room, galley, engine room, control room etc. Took some token pictures of P 'firing' a machine gun.
At the marine park area, we also went to the memorial site of the Arizona. Some 900 men are entombed on that ship so it was pretty quiet and respectful there. They have done it all really well.
All in all, massive but fantastic day!
