The bridges, buses and trains were shut down in Manhattan. I remember going in a coffee shop, a CVS and a pizzeria. Not sure about the pubs. I tell you one thing.. I bet all the hot dog and halal vendors disappeared and went into hiding
When the planes actually hit, I was on the bus somewhere in Manhattan. I went to college on 59th and 10th. At around 11:00am, the school let everyone out, it was unclear what happened. I was stuck in Manhattan until 3:30pm, when the trains started running again. I was on Madison Avenue, about 2 miles away. You can see the smoke if you looked South.
