Question on Darkness

[mcrowder]

Partially smartass answer, but true: I call for darkness when it becomes apparent that the lights will not turn on. Honestly - I've never had an afternoon/evening game at a field that didn't have lights. I guess I'm jaded. I have occasionally paused a game waiting for lights to come on, and I suppose my standard for that is about what would answer your question.

To answer your question, however, I think that I would be rather strict if I was on a field without lights, as you certainly don't want the lack of light to affect the game. If I can't see the sun (or where the sun is behind the clouds), then it's probably too dark.
