Wow. I had a consulting job in lower Manhattan that ran from November, 2001 to January, 2002. It was an odd time to be there- they were still reeling from the shock and businesses were trying to get on their feet again. I took the ferry from Hoboken to lower Manhattan and always paused for a prayer as we passed the wreckage. I knew two people who died in the attack (more who survived, fortunately) and my main contact at the client had lost a son in 2 WTC.
Glad to hear the PATH is running there again. It almost makes me want to go back to the East coast and check it out.
