Cover that lamp post!

A bit off topic, but this seems like a worthy little project to raise public awareness of the impact of light pollution. 

I remember growing up in Dallas in the early 1970s (yes, I'm dating myself) and having no trouble seeing the rings of Saturn on a medium-sized telescope. When I visit there now, no way you could have the same clarity of seeing. And the problem is getting worse. According to the International Dark Sky Association, outdoor lighting is increasing by 4% a year in the U.S. - faster than the rate of population growth. This unfortunate side effect of urbanization is wholly unnecessary (there are better ways to install outdoor lighting that minimize upward leakage) and wasteful (8% of U.S. energy use is for outdoor lighting, most of which doesn't go where it's intended).
