I just went last week. The whole place is awsome! Get there early and take your time. There is a lot to see. The best for me was the B-29 "Boxcar" that dropped the second bomb on Nagasaki. They also have "Fat Man" and "Little Boy" replicas i assume right beside it. I need to go back sometime by myself. My 3yr. old son was getting alittle testie toward the end so i didnt really check everything out. To anyone that hasent been its a must do!
