Light v. Dark - Tucson, Arizona
Tucson, Arizona, actually has city ordinances that help control light pollution. Although I've been there many times, it's very easy to get turned around at night with no street lights. The outlying towns are almost pitch black at night.
"The purpose of this code is to preserve the relationship of the residents of Pima County to their unique desert environment through protection of access to the dark night sky. Intended outcomes include continuing support of astronomical activity and minimizing wasted energy, while not compromising the safety, security, and well being of persons engaged in outdoor night time activities."
Nonetheless, a city with a population of over 500k is destined to produce light that emits high into the night sky. This image clearly illustrates the Tucson's lights fighting for room in the night. The foreground was lit up by a car coming down Mt. Lemmon.
