Hope she's ok, but that doesn't excuse the fact that people are constantly in and out of seats at all minutes of the game.
Where she just happened to be, those are $200+ seats. Last thing I want is someone standing there in the middle of a pitch.
This is a stadium wide issue and I addressed it with the Pirates.
Not that it matters, but I took a video of Pedro Alvarez's home run on opening day and right as the pitch was thrown some guy walks right in front of me going back to his seat.
Not only does the people who are rude and in and out during the game disrupt the view of the game for those nearby, but that person or people take the attention of those around them away from the game and when you have projectiles that need attention.
Either wait until there's an out, or after the inning is over before making a move.
