This is something I have in the hopper for when I have nothing else to say... But given all of the G20 hype it may be interesting to read. The following once written about Pittsburgh. Seems to me that the situation has been reversed. Read this and then note the date:
It would seem, too, that a great deal could be done to advertise the advantages and good points of the Area (Pittsburgh). When the city is mentioned many people who have never been there say it is smoky, dirty and hot in the summer.
