I'm still going. Twenty minutes from my shore house or twenty minutes from Chester makes no difference to me.
Not sure if that's the reason, but speculation is running wild. This past Friday, Maiden played Camden and Coldplay played Philly. Even if the Phillies played home, they could have done this.
Something else to speculate on: Ticketmaster's site has all of the seated section listed as 'Sold Out'. Gonna go out on a limb and guess that they are transplanting the Chester ticket holders in these seats.
Twenty days to figure this out.
