Great Wall of China 1--Badaling

Second day. Folks I met on the boat are taking a tour to a section of the great wall, just an hour or so out of Beijing. I want to go immediately, so I decide to join them. This is the reason I've come to China, that and it's between Japan and Nepal.
The great wall doesn't dissapoint, but the tour does. I start making a plan to head to another section of the wall on my own.
