In life there are a few different categories of bucket lists. For WWII history I’ve visited/seen a few cool things. Got to see the pill boxes at Kwajalein, it is mentioned in the biography Unbroken. Amazing to see diesel engines from WWII just sitting on the shore.
Getting to go aboard the mighty Mo’ and see where Japan formally surrendered ending WWII. But probably the most incredible hallowed ground (or water) is the USS Arizona.
