Depends on basement. DW nicked the idea of pitching in living room, where is perfect circle when we need him?
If she will play in these condition, she needs to practice in these conditions.
Our basement has less useable room than our living room.
I would not let me DDs play in 12° weather, with a wind chill of -3°. That what is by us right now. Forecast high is for 19°, with a wind chill of 3°.
Does any organization allow games to be played in weather like that? Are there guidelines for when games are to be cancelled because of the cold?
