Explanation:
Chicago, in a way, is like a modern
Stonehenge.
The way is east to west, and the time is today.
Today, and every
equinox, the
Sun
will set exactly to the west, everywhere on
Earth.
Therefore, today in
Chicago,
the Sun will set directly down the long equatorially-aligned
grid of streets and buildings, an event dubbed
#chicagohenge.
Featured here is a
Chicago
Henge
picture taken during the
equinox
in mid-September of 2017 looking along part of Upper Wacker
Drive.
Many
cities, though,
have streets or other
features that are
well-aligned to Earth's spin axis.
Therefore, quite possibly, your
favorite street may also run east - west.
Tonight at sunset, with a quick glance, you can actually find out.
