Spent a wet and rainy day at the Great Wall of China, one of the Seven Wonders of the World. This section of Wall was built 1404 BC. It was a difficult 550 meter climb to reach the Wall, sometimes at an 80-degree incline. We hiked about 1 1/2 miles of the Wall; that, too, was a difficult climb. When the Wall was built soldiers used a variety of steps - depth, width, height. The view was incredible. The thought of the 3,500 years of history that took place on this very place was an incredible experience. It was an awesome day.
