So, a few observations....
1st-PEK airport was unbelievably hot. It felt like there was no A/C at all. The jetway was the worst. Oh well.
2nd-I was pleasantly surprised to see the steps China is taking to combat vehicle pollution. I don't think any of the scooters I saw zooming around on the streets and sidewalks had gas motors, and there were very few older cars on the road. Baby steps to be sure, but good to see.
3rd-The drivers are actually better and more disciplined than Korean drivers.
4th-Spitting of phlegm onto the sidewalks. Lots of spitting...(of course, Korea is almost as bad).
5th-Taxi driver on the way back to the airport on the final day didn't try to rip me off. Always a nice touch.
6th-Lots and lots and lots of old people, and relatively few kids (much like Korea). I fear what the economy will look like in a few years.
