Tonight, at twilight, the city of Manhattan will perfectly align with the sunset. The setting sun will shine its light down the the exact center of east-west streets. Manhattan's grid deviates from the cardinal points by 28.9 degrees. If the city were laid out with the compass in mind (instead of the geography of Manhattan island), this effect would be seen on the solstices, which are the only days that the sun sets precisely in the west.
If you miss it tonight, you can see this again in July. The two occurrences are evenly spaced, on either side of the solstice.
Sometimes I worry that we humans think of Nature as something that only exists way out in The Country. Thinking that way misses the point.
We live in the natural world.
(We've just paved over much of it.)
So, even if you're not in New York City this evening, do take a moment to notice nature. Listen to a bird. Stare at the sky. Notice the leaves on a tree. Stand on the sidewalk, and immerse yourself in nature.
