No problem Steve. It was really a great experience. The virtual tour on the website could explain the stuff better than I can, but the things that stood out for me, was the WWII era equipment. They had a room that was set up to depict the conning tower of a fleetboat, complete with working periscopes (they looked pretty authentic to me) and a TDC. I played around cranking the dials, and exerything seemed to work. A cut away Mk14 torpedo, 20mm AA gun, an TBT set up on a pedestal, plus some battle flags from various subs added to the collection. And let's not forget the Nautilus! All in all a great day!
