Went to NYC last year for vacation during the Canadian Thanksgiving weekend (Columbus Day in the US).
After some considerations decided to post a photo to commemorate the 10th anniversary of 9/11. Some may find looking at twisted metal, rubble & debris, even photos of heroic firefighters in St. Paul Chapel across the street too distressing.
Know someone who worked 4 subway stops from the WTC Site. On the fateful day that person probably took a taxi when subway service was suspended. Some people feel distressed that they cannot walk within the vicinity of the site.
