Even after walking past Ground Zero to work for the last three years, I still mentally picture it as a stalled construction site around an empty hole because of the many delays and controversies in rebuilding the World Trade Center. And so its progress still sneaks up on me. Just last week, while waiting for cart food, I realized for the first time that I couldn't see the top of the 3 WTC without tilting my head up.
I looked through my personal archive to find the oldest photos I've taken of the WTC site. In August 2011, I tried recreating those photos by eye. The before and after can be seen below. Click and drag the line to see before-and-after.
