I'm always willing to hear contrary evidence, but it seems to me that it would've been a lot of work to pull off. Who brings a legal pad to a music festival and write 6 pages of semi-coherent organizing notes in the middle of a clusterfuck?
I'm inclined to believe it's real. The people I feel worst for are whatever middle management they had who undoubtedly were told to "make it happen." Trying to coordinate that with the resources they had, knowing damn well there was no way to do ANY of it, much less get through one night had to have been stressful as fuck.
