Dark Sky Advocate Observing Club Results
Business Letters I Sent on August 3, 2010.
Letter 1 - I sent this one to our local Target store because of their responsible lighting practies.
Letter 2 - I sent this one to the Colorado Department of Transportation about the glare of oncoming headlights for a very busy local divided highway. The oncoming lights always bother me at night.
Letter 3 - I sent this one to the Broomfield Events Center to encourage them to use softer lighting after dark on their large, roadside advertising sign.
