Backup: Visible from space...

BACKBLIP: I was unable to blip while I was away in China for over two weeks in November (blipfoto is not accessible therge) and was busy when we came home so I missed a lot of daily blips. I'm attempting to catch up!
Just as with yesterday's topic, today is another Chinese spectacle we'd both always wanted to visit, the Great Wall of China. And it is truly remarkable, hugging the mountain ridges in both directions as far as the eye can see.
