I've heard about a man and woman who are walking the length of the Great Wall of China, approaching each other from opposite directions. Every time I think of them, I see them from above., with the Wall twisting and winding through the landscape and two tiny human figures moving toward each other from remote provinces, step by step. I think this is a story of reverence for the planet, of trying to understand how we belong to the planet in a new way. And it's strange how I construct an aerial view so naturally.
