I have boarded the U.S.North Carolina on several occassions.
She currently resides grounded in Cape Fear River near downtown Wilmington, NC. Sitting in the 16" gun turrets is an interesting experience.
The park has a fence of 16" projectiles. You have to see them to realize just how huge they are.
I sat at the bow and looked down and realized that falling off a battleship would be an unfortunate experience. It is a long way to the water.
