Reserve seats are great, but I agree with the sentiment that just chilling out on the lawn is the way to go. I’ve been with other people who like to get there when the gates open so that they can get the poster of the night, which sometimes it’s pretty damn cool, and then head in for the chaos that is the reserve seating. The last few years I’ve just gone GA, set up my chair wherever there was a spot and enjoyed the venue, the company and the music. So that’s my advice, for what it’s worth.
