My favorite photo: the Great Wall of China, by Johnny

This is one photo taken in June of 2010. I went to China for work; I had to test vibrations in wind turbine. Before I was in there, I studied this great monument. I was impressed by the quantity of workers that died to end this work. I found these gigantic steps and somewhere there weren´t, or they had been deformed. Million of persons visit this wonder of the world. I have nice memories.
