CLEVELAND -- Yes, that was a deck cannon you heard being fired on Lake Erie near the East Ninth Street pier today.

The World War II submarine, moored between East Ninth Street and Burke Lakefront Airport, was the site of historic actors portraying America's Founding Fathers Benjamin Franklin, John Adams and Thomas Jefferson.

About 11 a.m. Friday, the Declaration of Independence was read aloud. The 312-foot submarine's five-inch deck gun was also being fired hourly.
