I took a more mundane route. I called the local lighting
company (We have a private one in our town) and asked for
a timer on the light. Three weeks later, there was a truck
outside my house putting it on. Now the light is off from
9:00PM - 1:00AM every night.
Sometimes you just have to ask.
Would never happen here in San Antonio only place to get electricity is CPS, it wouldn't make much of a difference too I'm afraid :-/
I'll have to try the sketching when I get a chance to visit any of my family outside of town/state (would love to visit my cousin up in El Rito, NM...her property has an amazing and completely preserved view of the nightsky.
