Ohh! I was looking at completely the wrong map, thanks for pointing it out. (I was looking at the smaller one.)

Wow. That's... the way people were going "People should have known!" I'd assumed that the room wasn't on the map. How the hell is someone who doesn't work there meant to be familiar with it to that degree? Even if I'd been in Soldier Field the day before, I'd assume I'd just missed Stagg Field at the time.
