Tompkins Square Park, NYC
Here's a book I'd like to own, Mannahatta, a rediscovery of New York at the time of Henry Hudson's landing 400 years ago.
Many years ago when I was considering buying an abandoned house facing Tompkins Square Park with no for sale sign, I went downtown to see if I could find the owner.
I never found the owner, but what I did find were the most intricate, aged, fascinating maps of the City of New York. Where the Park is now, filled with trees, had once been the site of a long, narrow stream.
