Going up on the Great Wall was one of those things I never, ever thought I'd get to do, and it's still one of the coolest things I've ever seen. Forbidden City wasn't as interesting, but still glad I saw it. Another reason why TPR trips rule, you get to see all sorts of cool stuff along with all the parks!
The salespeople at the various factories are REALLY annoying. I chose not to spend money at the silk one when one woman would not stop bothering me. I also found the street merchants in China to be the most aggressive of any country I've been to. I remember being accosted by some while crossing the street. Anyone that's seen people drive in China knows the last place you want to stand around and buy things is in the street!
Loving this report. Really glad I went in 2008, because the pollution was non-existent compared to your (and others) photos. Such a shame, as they showed they could control it if they wanted to.
