We were passing through Harrisburg, PA, and saw information about this museum in our AAA guide. We were very impressed after we got over our surprise that this "National" museum was located in PA instead of somewhere in the south! About 10 years old. Building is beautiful, and the exhibits are outstanding, especially the videos throughout, following several characters from the beginning of the war until the end as you pass (chronologically) through the exhibits. Very reasonable cost. Even 13-year old boy enjoyed it.
