That is called Duke Tower. An office building close to the campus of Duke University.
I am not exceedingly fond of it, although it is a nice looking building. The reason it appears in many of my pictures is that there is a large area of vacant land here where I fly very often. It is about a 3/4 mile square and completely unused. At one time there were shopping centers on this property that have all been torn down and the area fenced in. Here I can fly in-interrupted without ever having to worry about flying over any people or being harassed by anyone. I do not like an audience.
