Ending game's due to darkness

[AtlUmpSteve]

Horse hockey. Determined sundown has limited affect on when it may be too dark to continue play. Trees, clouds, mountains; there are any number of factors that COULD affect play.

The simplest and (IMO) most obvious way to address darkness as a pregame possibility is to to state that when/if it becomes too dark to to continue safely, IN YOUR JUDGMENT, you will end play. No specific time for a coach to play as a factor, not "we won't be able to finish so we won't start this inning"; you play until you can't, and the plate umpire has the final word on when that is.

Anything else gives the teams tools to play with that have no legitimate place in softball.
