If you fly over the area at night you'll likely find that most of the
streetlights are not "glaring upward". You'll see nicely illuminated
little circles of ground with no bright spot in the middle.


I just flew from chicago to albany NY the night before last, and I was
amazed at the number of lights that still DO have a bright spot in the
middle. It was noticable enough so that the nicely illuminated circles of
ground (kinda orange, actually) were definitely a noticable minority.
