I don't know, I went to outside lands(SF) for three years straight 2011-2013 and it wasn't too bad, not being able to leave and come back in during the day was horrible(they wanted you to eat over priced food inside the festival) but everything else was pretty great(water stations, bathrooms pretty clean for a festival). I also don't hear alot of bad stuff around Cochella and it has truly massive crowds. I think woodstock 99 really was poorly run which is why we haven't seen another one since.
