In the late 1990's, I had gone to the observation floor of the World Trade Center. I was excited to be able to now go to the observation floors of the new building. It felt like coming full circle. The elevator ride up goes by fast, but watching the simulated changes of the area was great. Once you get to the top, the views are wonderful. I didn't spend a lot of time there, as I did just a quick run-through. Upon exiting, I ended up in the adjoining Oculus, which was a very happy accident. The architecture is wonderful. After a little research afterwards, I now realize that I should have gone outside to see the Oculus from that vantage point also.
