Named after a whale and not the Arkansas Razorbacks - the submarine called the "Razorback" is quite an enlightening experience into the "silent service" of WW II. Tours of it are provided daily at the Arkansas Inland Maritime Museum at North Little Rock. Our tour is with a crewmember who knew the sub all too well. The so-called amphibian duck boats were used in most of the major battles during WW II, including D-Day. They now serve as tourist attraction rides in quite a few cities, including Hot Springs. The duck boats' transformation though from a military vehicle to a tourist ride, is quite the story.
