I have to add my "me too" regarding the good crowds. Coming off the heels of Outside Lands and its apathetic crowds with no courtesy or self-awareness, I wasn't sure I really wanted to go to another festival so soon, but the crowds were good at everything I saw. There were for sure douchebags here and there, but it was isolated instances with individuals (which can probably be chalked up to being too drunk/fucked up), NOT dealing with a crowd full of bad behavior. It seemed like most of the audience were serious about show-going, ie, almost no talking during sets, people were familiar with the acts and their music, and were very in the moment (lots of people dancing along, not that many people on phones, etc). Really, this is a different experience than almost any other LA area show I've gone to. There were even a few locals who struck up conversations with me, along the lines of, "See? Not everyone from LA is awful."
The venue could definitely use work. This year's stage layout was better in terms of sound-bleed, and the "Carrie" stage was easier to navigate than last year's layout, but I hated the orientation of the dance tent. Especially coming from the stages further left, there was usually a bottleneck to get into that area, since you had to walk all the way around to the other side, or else walk over puddles of people sitting on the hill/under the trees in front of the tent. Last year's layout was a lot better. I also missed there being lots of sitting room on the sides of the tent. There were a couple of sets I walked away from because it was too crowded to really get into the tent. That's the only stage that seemed crowded to me at all this weekend.
The dust is killer... even wearing a bandana over my face, I've still been coughing up brown gunk all day. The rubber mats over the front part of the stages (in front of the soundboard) helped a lot, but it was dusty as hell walking around, especially at night. I also felt like this year, there was not much space to sit down to eat or rest. The beer gardens were pretty crowded each time I went into them, and it was hard to find a spot on the ground to sit where there wasn't constant foot traffic. Like others mentioned, it felt VERY crowded to me in the festival, yet oddly not very crowded at any stage (except the dance tent for a couple of acts).
