I think my desire to imagine a future for this site came out of trying to come to terms with the emotions that day aroused.

I hope for the experience of people standing together, turning their backs to the city and facing this, and hearing the leaves rustle. Well, maybe it won't be as bucolic as at the Brooklyn Navy Yard, but I know you will feel removed from the city.

I'm a little more measured. That sense of urgency I thought accompanied things - it can take a little longer. You have to take the long view.

New York was a place I wanted to live and work all along. If I wasn't going to live in Israel, I had to live in New York.

I pushed the process forward by saying, 'We should do this, this, and this right now. Please find the budget for me to find a structural engineer, a mechanical engineer, a civil engineer, so we can do the preliminary work.
