Bushes Growing on Top of Tower --- As hard as it may be to believe with all the advances made in the 20th Century, in 2009, an additional 180 miles of previously undetected portions of the Great Wall, built during the Ming Dynasty, were discovered.  My personal experience on the Wall makes me believe that with the extreme remoteness of the Wall and its steady rate of deteriorating back into the earth, there are many stretches of the Wall that are nearly gone and will never be known and other stretches that are so well hidden they will never be discovered.  As strange as this may sound, I have no doubt that there sections I had crossed that hadn't been seen by man in hundreds of years and may never be seen again.
