Nice. Truk Lagoon is the home of the I-169 Shinohara submarine.
I've been so lucky as to "explore" the area around Kehlsteinhaus in southern Germany, and we also went to see the house itself - fascinating experience. I bought myself a really good book about the history of the house, which I'm happy to own today.
I'd love to go to Germany and see some of the historically more interesting places - Berlin, Dresden, you name it, if there is a museum that contains anything about WW2, I'd prolly go see it.
France and Normandy could be interesting as well, although I know from a buddy who's been to Normandy, that the place has developed into something that suspiciously looks like a tourist trap...too bad for a place which hold such great significance for anyone with an interest in the history of WW2.
Poland and Russia (Stalingrad anyone?) could be very interesting too, even though I know that some of those places in these countries can have a very tough, sometimes even nasty and decidedly grisly history.
But I think it's important to learn, and to pass on what you learn from Europe's past mistakes - that's my main reason for wanting to visit those places.
And yes I'm also incredibly curious, as I believe that knowledge and the will to learn is power. *steps down from soap box and curtsies*
