there are still some pretty good tickets available from what I hear. I was at a Bears game this weekend and they were pushing it, also were saying they are going to have a fanfest before hand.
The only lame part about the tickets is, you are forced to buy tickets for the actual game (sunday) and the alumni game (saturday) - so if you're coming in from out of town, you may want to look at a hotel.
Great place for an outdoor game and sporting experience. That stadium has played host to a lot of NFL greats who've played in the Big33 (Marino, Namath, Montana, Kelly, Dorsett, just to name a few) and it's right next to the old Hersheypark Arena, which is where Wilt Chamberlain recorded his 100+ point game.
Just wanted to throw out some pointless history. :^)
