I will start by admitting that I didn't actually take this photo, but it is an impressive (depressing) example of light pollution:
On the left we have a "dark sky" photograph - a 'naked-eye' photo from the ground under good observing circumstances ... while on the right is the same region of the sky, taken in "the teeming metropolis of Orem, UT at the heart of the Utah County megalopolis comprising about half a million people." I'm not quite sure where JP Stanley is from* to call Orem, Utah a "teeming metropolis" but no matter - the comparison is striking.
* oops, turns out he is from Orem. hmm.
P.S. This isn't really Brian, but it fits the category.
