light polution

this photo was taken from a nasa site.

i was reminded of the map the other night when i couldn't sleep and was walking through the house.

in my room there is the light from the smoke detector, the powers strip, printer, cd player, computer. in the rest of the house--more smoke detectors, power strips, my sister's computer, the bathroom night light, stove , tv , tuner, dvd player, and sometimes the battery operated candles we have in the front room windows (sometimes we forget to turn them off). The house is never really dark unless the electricity goes off.
