An evening pause: From the youtube webpage: “On a remote island hours away from Key West lies the largest masonry structure in the Americas: Fort Jefferson. Built with 16 million bricks, but never finished, the fort served as a prison during Civil War. In 1935, President Franklin D. Roosevelt, upon visiting the island, named it a National Monument, and in 1992 it became part of Dry Tortugas National Park.”
