It is a wonderful, chilling, sober place to visit. My GF's grandfather was in the navy, stationed at Pearl Harbor during the attack....he was having his appendix taken out on Dec 7th, otherwise he would have been on his ship. He survived the attack (and left the hospital right away to help with the fight/recovery) and WW2, but they thought he might have died during the attack, as it was a few days before they got a full count on where everyone was. It was really cool to be able to talk with him about it.
RIP Cliff Gregory.
