Getting into Penny Arcade Expo's flagship show in Seattle, on Labor Day weekend, is notoriously difficult if you trek up there without a pass. The three-day variety for PAX 2011 is now officially sold out, according to the expo's official Twitter feed. They've been processing some refunds, freeing up stock incrementally, so there's an off chance passes still are available. But if you waited until now to get your money down, you're probably SOL.

Bought mine they day they became available thankfully. Unfortunately, there is a chance I could have a sister having a baby right in the middle of PAX, which could keep me from going.
Oh, and it's the weekend before Labor Day this year, not on Labor Day weekend.
