As opposed to popular belief, the New York street grid is not on the North-South axis. It is actually 30 degrees off. But twice a year the sun's axis is parallel to the street grid. On those days, the sun sets straight down the street so if you go to the far east end of a street that goes all the way across the island (like 34th or 42nd Streets) you can watch it sink straight down across the whole city.
I thought it might be fun to see how it looks in my neighborhood.
I hope you like the results.
