THANK YOU so much for finding and posting this. I'm a local who has been intermittently lurking here since the first week of the case and all the "Tucson is shockingly dark and scary" comments have been making me a little nuts (and more than a little sad). One of the many, many things I love about Tucson is that its a dark sky city, but I've never even been really aware of a specific "ordinance" because it simply isn't true that, as one person said here, the government dictates that people can't have lights outside their houses. I haven't lived anywhere here where people don't have lights at least outside their front doors if not other doors, plus motion-detector lights and so on. We have lights outside all our doors on our patios, under awnings, as well as solar pathway lights that shine down on the pathway. We also have down-facing streetlights, but we live near downtown, not in the outskirts. My parents live in a different area of the Catalina Foothills and have plenty of light close to the house.
Perhaps more importantly, I've lived in some so-called sketchy areas of town and our current neighborhood has much more crime than the foothills, but I've never felt like Tucson in general is a scary place to live. To be fair, I also wouldn't go out and walk my neighborhood alone at night ...
So thank you for finding the facts, here. Plus, I learned a couple of things. I didn't know amber lighting was better, plus now I know the neighbor across the street with the very bright light that shines across into our yard is probably not supposed to do that.
