There are a number of Messier objects in Ophiuchus, along with some great double stars and other clusters. But two that are right near each other are Messier 10 and Messier 12, globular clusters both.

Do something. Change a bulb. Replace a fixture. Get politically involved, or call your electric company. Be polite, but be PERSISTENT. You probably won't get results on the first, second or even third try. The streetlights around me took four tries and over a year to get changed. Even if you just do ONE THING, it's made a difference!
If a flowerbed has a tall clump of grass growing in it, then that grass is a weed, because it is a plant growing in an area where it is not wanted. Or, as shown here: Grass on a roof.
