Manhattan Neighbourhoods

The only time I was in NYC I was 14 years old and the only things that really caught my interest were sites like the Empire State Building, Central Park and the United Nations. I had no feel for how the streets were laid out or what the various neighbourhoods were called. But now, 60 years later, having read a lot of novels set in NYC, I'm a bit more interested in how it all intersects, so when this map popped up in my Twitter feed, I was delighted and fascinated. It will definitely enhance my reading. I have it on my phone so I can zoom in for a better view.
