Below is a photo that my son took at Ground Zero three weeks ago. He tells me that the photo does not do the area justice (looks in two-dimensions pretty much like part of a typical city skyline). But he has been in NYC many times during his young life, and he said that a 'different atmosphere' permeated the area....that the reverence and grief was palpable. The blaring of car horns was all but absent. The people with whom he spoke (both tourists, and natives) were cordial -- many of them almost behaving as if they were visiting hallowed ground.
Note (if you can see it) the 'We salute you' banner in the lower left hand corner.
I will be driving up to Boston in a couple of weeks, and intend to stop and see the area myself on the way. It will do my heart good to know that those who gave their all during our blackest day are that much closer to receiving an even more appropriate (and historically accurate) 'salute,' thanks to your efforts.
500,000 is just around the corner.:-)
