In college I was once in a desert field ecology class (distribution requirements.. it was not my major.. now I kind of wish it was), and I found myself bumping through Tuscon with a van full of stinky but amiable Co-Ed's late one night. Somehow it left an impression on me that Tuscon felt surprisingly small for the population I knew it to have, kind of, well, natural... and I remember someone mentioning or knowing there were some observatories up on Kit Carson Mountain, so I gazed up and had a look as we drove by on what must have been good ol' I-10. I never knew much about astronomy, but my dad had been in the Navy, and knew how to navigate by the stars, had even studied it in college. He used to occasionally teach me a constellation or two. Given this small family preoccupation, I liked to pick out little details like knowing the observatory was there, and file them away.
Fast forward a few years, and I am a Municipal official of sorts (everyone makes mistakes in life!), and something crosses my desk about a new type of Light Fixture that the state government wants me to set up a demonstration project for. I have to find a place to put something like 7 so called "Full Cut Off Lighting Fixtures". There was so much jargon in government that my brain took it in stride (it's a street lamp!), since I was learning about everything from the constitutional law to street plows. I read the description that the state legislature had passed, something kind of exotic and progressive called Dark Sky Legislation, to mitigate a so called Light Pollution Phenomenon ("What won't they think of up in the capitol! Good for them, my brothers in utopic striving!" I thought to myself, in all earnestness.), and I think my brain was about to move on to other business as I moved further down the description, when I found the allegation that flooding street lamps have not only social consequences, but health consequences as well, and that people sleeping in rooms with too much light from street lamps can suffer from hormonal imbalances, mental health issues, and even circadian rhythms and menstrual cycle disturbances, and that it can be a contributing cause or the cause of their cancers and other infirmities directly or indirectly. Realizing that I work in politics, it might make sense that I fixed on one important thing: this might be something else to blame my girlfriend's moodiness on when I am in the doghouse again.. hot dog!
