What do you like about ****** photographically?

Now here's a question you can answer without ever having visited a city (although visiting sure makes it easier): on sight, strictly the way the city looks, alone, what is it you like about major American cities shown here with photographs on this board...other other pictures or from being there yourself? I'm throwing out attractions, business, culture, restaurants, climate, entertainment...even the people (ouch!!!!!!) and just plain looking at each city. Visually. The eye as a lens. What exactly is the visual appeal of the ones that really grab you?>
