TF2 at Eastern State Penitentiary Today

I just received a heads-up from BP that he spotted activity at Eastern State Penitentiary where "branches and trucks [are] moving inside the building." This info has been verified by Philly.com:

Transformers 2 cameras and crew have been all over (Fairmount Park, University of Pennsylvania) and today are due inside Eastern State Penitentiary, while Rittenhouse Square will double as Paris later this week. Saturday is the scheduled Philly wrap; next stop: Princeton.

Based on the info from the other day, that indicates the shoot at Rittenhouse Square will occur on June 19th, this Thursday.

Thanks to BP and Jim for the info.

Update: It appears that the shoot at Eastern State Penitentiary will be on Friday, assuming that is why a location that is normally open "every day, twelve months a year" except holidays is suddenly announcing "Please Note: Eastern State Penitentiary will be closed to the public on Friday, June 20th." Now I don't know if that means shooting will also occur in a more limiting capacity between now and then but considering that apparently TF2 production is shutting down the whole site, which indicates that the location has a larger part in the movie then previously suspected. Thanks to Jim for the heads-up.
