A lot of us think that it would be exciting to go to China and walk on the Great Wall. I did.
It is amazing in that it is a massive and very long structure.
The trek is exhausting if you have to walk to it from the bottom of the mountain ridge.
We were fortunate because we got there early and the bus could go most of the way to the top.
Later on the small parking lots near the top get full and the people have to climb from farther down below. Many people died to build it. It can even be seen from outer space!
