I spent a lot of time in the twin towers. There was actually a civil court annex with a few courtrooms in there for a while. There were also many law offices. My father's cousin was a steel worker who worked building the towers for years. I remember talking to him about how scary it must have been working on buildings that tall. He said that when you go to work every day, the increase in height was so gradual that you don't notice it. I doubt that would be the case for me. I have a fear of heights.
