When there's low cloud I get no illumination from the heavens, and very
little from the nearby cities. Since I walk in fields often occupied by
livestock I really like to see where I'm placing my feet.

I have noticed that on a wet night there's more light reflected up to
the clouds in the urban areas.

A few evenings ago we appeared to have two sunsets, about 75 deg apart.
