This seems to happen every time there's a sellout. I think they start with an initial approved number of tickets and when it sells out they go and get permission from someone with Grant County and/or the city of Quincy to raise the festival capacity. Maybe it's just me, but in my five Sasquatches it's definitely seemed like some years they had a few thousand extra people. In 2009 every day it felt like I was in the middle of a massive sea of humanity and barely had any room to walk anywhere. It hasn't seemed as crowded since then.
