I didn't know Colorado had oil derricks!

Oh man, we have thousands and thousands of them!
The NE corner of Colorado is the SW corner of the Niobrara Shale, so the oil and gas industry has been bustling out here for the past decade - however, the old derricks are quite old. There are some pretty neat relics way out in the grasslands, many of them no longer in operation, but still standing and weathering away.
I'm not the biggest fan of the active rigs and new sites, as they spew so much light pollution into what was once a Bortle Class 1 night sky; and the trucks absolutely demolish the dirt roads... But their activity will settle down soon enough. When that happens I can only hope that the companies consider putting their insane flood lights on proximity sensors or remote switches that the tanker drivers can use, rather than just leaving their lights on all night like they do now.

Sensors and Arduinos cost pennies, surely you can't expect a multi-billion dollar corporation to pay for such expensive items?! (sic)
