Marble wall engraved with the names of all Colonial tournament champions. Many great golfers have never won at the Colonial, including Tiger Woods. Many others won only once. Hole number 5, and the other "horseshoe" holes are a big reason why. It is one of the most difficult holes in professional golf. Extreme accuracy, not just length, is the key to winning here. Due to the great difficulty, some great golfers choose to pass up this tournament. Many consider it the 5th major.
