all they are doing is avoiding a circus of people trying to catch HR balls. everything will be back to normal in two days i would think. if they dont want you to go somewhere, i guess it is their right. once they let one person do it, the floodgates open. maybe people were meeting friends, taking shortcuts, etc., but once it happens once it will happen hundreds of times. i think this falls into the fact that people (fans, ushers, everyone) arent used to having such a full stadium coupled with the bonds circus. many places will not let you into certain areas without a ticket. usually not the bleachers, but it is understandable. im sure the ushers were instructed to be strict, and i am sure the ushers like their jobs...so they did. as for the sign, i could see them taking it away. someone (dont know who) wasnt telling the whole story if it led to police threatening arrest.
