It doesn’t sound by accident like Stonehenge. Two times a year, the sunset aligns with the grid of Manhattan, so you can see her all the was through the cross streets. In this year, it is the 30th of may and the 12th of July.
Today, we should have seen the half of the sun between the buildings of every cross street, like the 19th, where I was waiting, well, not alone. I chose this street because of the new surface, which reflects the light very good.
