Here's how it goes. Find a picture of a city, could be the skyline, an overview of a section, whatever, and everyone has to guess what city it is. Then whoever guesses it right posts the next one. Since it's rather tough to name a city looking at a picture of some buildings I like to give clues after every wrong answer (further west, further south, what region it's in, etc etc) but that's up to the discretion of who's turn it is. Any rate, I'll start with this one.
