When you arrive to the visitors center (which is sinking, I might add and I am so not joking!), they have exhibits and displays chronicling everything about the attack. They even have a short film with actual footage from that morning that you can watch. But that doesn't compare to the feeling you get once you step off that ferry that takes you to the Arizona Memorial.
When I last visited the memorial with my great uncle, I remember being at the observation portion, and right after we had thrown our leis in the water, a big glob of oil rose to the surface. It's a haunting feeling, knowing that it's been there all this time...just like the men who died that morning.
And no words can express the feeling when you walk into the shrine room. Just sadness and gratitude for all these men who died defending the country.
