I saw the U-505 in Chicago, but didn't get inside (forgot to book tickets in advance
). Also toured the Bowfin in April during my honeymoon. I got an awesome external pic that I now use as my desktop. That same day, as we toured the Missouri, the USS Kentucky, SSBN 737, left Pearl for destination unknown.
I would gladly post the pic if someone would be kind enough to let me know how to post a digital image here
