My speculation is the LiveNation boys are going to discover that spending $$$$$ on U2 is not going to solve their Bonnaroo attendance issues. A few things at play from my POV:
1. I'm guessing we are mostly over 40, and there's very little at this festival for us besides U2. No Wilco, MMJ, Dawes, Petty, DMB, etc. (insert dad-rock joke here) as there has been in the past
2. There exists a general mis-perception among this age group, of which I am a part, about Bonnaroo that involves drugs, difficulty, expense and inconvenience. This is even among people in Nashville (where I have lived for 20 years) who really should know better.
3. That said, Bonnaroo is kind of a pain in the ar*e to access and yes it's hot AF -- and yes it ain't cheap. So why not drive to Louisville which is less than 3-hrs away? Seriously I cannot believe LN allowed that show to happen.
I am an 11-time Bonnaroo veteran. My experience allows me to look past all the challenges that exist and be confident this is going to be an absolutely epic performance on a massive scale. I'm very much looking forward to being there, but in the past decade I've witnessed an evolution in creative direction of this festival that is now on stun given LN's involvement. And I fully expect this year, my 12th, to be my last year on the farm. I'll go down singing.
Also hedging my best and going to Seattle & Chicago as well.
