It's like crossing into a war zone. But the line is definite. On one side, you have normalcy, power, and everyday life. Maybe the sidewalk is a little wet or there are a few pieces of trash. But less than 20 feet away, nothing is recognizable. The stores are dark. Many are boarded up to ward off looters but a few are open, offering a bit of food and water to passing cops and marines. Just a few steps across the street and you're in a different place in the same city in New York. It's the normalcy everyone is headed towards.
It's two different worlds. All you have to do is cross the street.
