Ever been on an aircraft carrier? Exploring the USS Yorktown, a WWII ship, was the best part of visiting Charleston.
It is docked at Patriot's Point. The ship was massive, just huge. It didn't feel like we were on a boat because it was enormous. To give you an idea of how big, there were 15 planes parked on the flight deck! The Yorktown has plane elevators in the fligtdeck to lower the planes up and down to the Hangar deck for repairs. Staircases were almost as steep as ladders. We saw the engine room (which I did not like because of the screened walkways and the narrow space the sailors had to work) to the bridge (where the captain and the navigator work). The ship had many rooms showing models of different ships and submarines and many photographs of ocean conflicts and naval battles.
Beside the Yorktown was a WWII submarine. It was never use in battle because it was not ready until the end of 1945. It had narrow doorways and was quite small. I can't imagine living there for months.
If you go the Charleston, you have to go to Patriot's Point. It's great!
