The coolest kind of building. Modern high-rises are marvels in engineering. They're also cool to work in. And of course, nothing beats a ride in an ultra fast elevator, or the wonderful view from the upper floors.

First floor to 107th floor in the #2 World Trade Center: Two minutes. You can see for miles in each direction. So many people are jaded by things like this, but I appreciate them more every day of my life.
