GPS track showing one week of walking during a vacation in Shanghai, China. Shanghai has got more skyscrapers than the entire west coast in the US, so it is not particulary GPS friendly. Especially when going by subway, walking a few blocks and then back down into the subway - usually the GPS did not manage to lock on to enough satellites to get any positions at all in between subway rides and going into department stores.
One week of walking the streets of Shanghai from morning untill evening and my shooes are just slightly dusty. In almost any other city they would look like this after thirty minutes and after a week they would have been light grey from all the dust.
Shanghai is an incredably clean city.
And I love the fact that I have not seen any trash being put out on the street. Seeing the sidewalks lined with garbage bags in Dublin was a cultural shock for me. In this respect, China is much less of a developing country than Ireland.
On the last day I found it - gadget heaven on earth: Cybermart (www.cybermart.com.cn). Well over one hundred technology shops in one large shoppingcenter. A large lan party like Assembly in Helsinki came to mind. Small shops next to each other with lots of salespersons playing Counterstrike while eating noodles, empty soft drink cans everywhere and electrical and network cables covering the floor.
