Where Did the Dark Go?

I didn't even know it had left.  But according to the just released "New World Atlas of Artififial Night Sky Brightness,"  one third of the human population cannot see the Milky Way at night due to the glow of artificial lights.
They call it "Light Pollution."

"Moreover, more than 80% of the world’s citizens and more than 99% of those in the U.S. and Europe live under an artificial sky-glow, or reflected light scatter in the atmosphere from the electric lighting below. This isn’t just a problem in megacities and urban areas. For instance, Death Valley is awash with skyglow from Las Vegas and Los Angeles, which are 80 and 150 km away, respectively.
“There’s almost no place in some of these countries that looks dark anymore, at least by this atlas’s estimates,” said Christopher Luginbuhl (Flagstaff Dark Skies Coalition).

Well, I know of one country Christopher could go to and live and never be bothered by "horrible light pollution:"
