When I was in NYC a couple of years back I was amazed that when I talked to New Yorkers that I could clearly see- for all their bravado about being big city tough- how much this attack is seen on very personal terms. For many people who were there on that day, witnessing the events first hand, it is still a wound that will probably never heal. Of course, New Yorkers are really a different species and unbelievably robust and dynamic.
I took classes not far from Ground Zero- although that term is, by no means, a small nor well-defined area. I would meander my way through the streets, stumble across something peculiar and suddenly be reminded of the event. A huge empty area in a crowded city, for example. A cross-beam left over from the wreckage now serves as a kind of symbolic survivor and gathering spot where people may stop and stare and pay their respects. Some people took pictures although I never did. The feeling you got standing there- of an injury remembered- wasn't something I thought could be photographed.
