A trip into China and around Hong Kong

Summary

More from my trip to Hong Kong. On this occasion I travelled on busses trains and cars. The pollution levels on the train were notably less than on the bus and in the cars. (you can tell by looking at the terrain on the Goolge Earth visualisation. CO level on this trip varied up to 6ppm which is relatively high even for an urban area. There are photos on this one so the KMZ file is quite large.
