The image was taken from encarta.com and then I slapped the X's on.
You can see Hackensack on that map, I slapped a red X near it. That's where I live.
On the map, I x'd the WTC, and then above that there are 3 X's close together. The left-most one is approximately where Pier 40 is; the one right and a little below that one is approximately Houston St. where I talked to the cops and was sent to Pier 40; the X above that is ~where I work, maybe a little too far south.
The 2 X's east of the park are approximately where the blood center and her apartment (where we were given the pillows and blankets).
