The sign reading: '- WARNING -- The Black Course Is An Extremely Difficult Course Which We Recommend Only For Highly Skilled Golfers,' is arguably the most famous in golf. 'The sign is gone,' Ryder Cup director Bryan Karns told The New York Post. 'The Ryder Cup will use a brand new (first) tee that's 40 yards in front of the existing tee. For fans wanting to see the sign, it has been relocated to the Ryder Cup Live Fan Zone inside Rockefeller Center in Manhattan that will be open Sept. 25-28, per The Post.
