I knew that this stop meant there was a lot of history to see, but this is like a center point in history. Fort Moultrie on Sullivan Island was under construction in June 1776 when it was attacked by the British and it still forced their retreat. After the war, it ended up abandoned. The fort was rebuilt in the 1790s and again in the 1880s as other wars erupted. It last saw duty when Pearl Harbor was attacked in 1941, but after WWII, it was left abandoned one last time. It has since been restored and is a historic place and museum. Leaving Sullivan Island, we stopped at Patriots Point where we toured a destroyer, a submarine, and the the USS Yorktown, an aircraft carrier. A great deal of each ship is open for the tour – engine room, control room, radio room, CIC, and the flight deck of a carrier. Just trying to think of how many planes took off and landed on that deck blows you away. Many types of those many planes are on display either on the flight deck or below decks, including my favorite, the Corsair F4U. For the sub, you enter thru the forward torpedo room and exit thru the aft torpedo room. Along the route, you pass thru about eight watertight bulkhead doors that were about 36″ high and 24″ wide. These were fun getting thru!
