I just received an email asking if I would amass a GTG sometime in June for Eastern State Penn. So I'll give them a call today or tomorrow and find out what their schedule is, how friendly they would be towards us, and if we can get cart blanche in some areas.
I believe you all wanted a week day gathering as well ? What day of the week would work best (keeping in mind ESP's schedule) ?
Also, dependant upon what ESP has to say, we can always go around Philly to some spots that I would recomend.

Keeping in mind the following dates on my calender:
June 10-11 - Manayunk Bike Race
June 24-25 - WWII Airshow @ Millville Airport

Its obviously too late to schedule anything before the 10th. So I imagine we would be looking at dates after the 12th.
