If you are ever on the Gulf Coast, stop by and tour the USS Alabama in Mobile Alabama. For one reasonable price, you get to tour the battleship AND a WW II Submarine. The entire time I was on the battleship, I kept thinking, "How does this thing float?" I understand the science behind it, but it is so HEAVY and so big. The WW II submarine is so SMALL inside. Talk about claustrophobia. I could never have served on one. They look much bigger in the submarine movies.
