Cleveland city officials say a submarine memorial will remain on the shore of Lake Erie.There had been some doubt about the future of the USS Cod Submarine Memorial because of development plans for the area. Memorial director Paul Farace says the sub draws many of its 25-thousand annual visitors from among people walking to the nearby Rock and Roll Hall of Fame and Museum. The Cod came to Cleveland in 1959 as a U. S. Navy Reserve training vessel. It sank 15 Japanese ships during World War II.
