The Bowfin Submarine seems to be an overlooked part of the Pearl Harbor experience, but it played a very important part in avenging the pearl harbor attack. Go to the bowfin museum and watch the video. I couldnt believe how many ships it took down during WW2. Its really cool to say you walked through a WW2 submarine. It takes special people to be submariners. This is a good stop if you have a long wait before your tour of the Arizona Memorial.
