City Shots

As some of you may notice I have been doing a lot of screenshots with GA planes and scenery. I want to return to the beginning as when I was shooting commercial jets in cities. I have always loved the way a jet moves. Now for the question. How do we screenshot in the big cities without having to worry about the ground textures around the big buildings being blurry? Any tips on how to capture shots around cities? I haven't been getting into the screen shooting mood lately either.
Thanks
