Will the roof be opened or closed?
It is amazing how often the roof at Miller Park is closed due to cool weather or the slightest chance of rain. When the roof is closed, it remains very warm inside and downright hot in the summer. They generally don't open or close the roof during a game, so the decision is made well in advance of game time. You can call the Miller Park Roof Status Hotline several hours before game time on any game day for a prerecorded message indicating if the roof will be opened or closed: (414) 902-4636.
