Thanks all! Some really great ideas. I'd love to take a carriage ride thru Central Park! I only want to go the ground zero because of the significance of it all. I almost lost my brother that day at the Pentagon.
I've ridden the subway when I was there back in high school. It was just something we wanted to do because it was so New York-y. We might actually NEED to ride it this time to get to some of these places!
