We're just three days away from a full moon and its reflected glow is giving the luster of midday to objects below. (with apologies to Clement Clarke Moore) In our darkened back yard, I cast a moon shadow. Now the song is stuck in my head and the fun fact that Yusuf Islam (formerly known as Cat Stevens) wrote that song in his early 20s, he had never seen a moon shadow because he'd always lived in a big city.
That is how you get from locking up for the night, to light pollution in four easy steps.
