Terrible set up for concerts.  For general admission concert tickets, they have the floor split into two sections and make the first people who arrive completely fill up one section before they open the second section.  This punishes the people who stood in line early and arrived first by not letting them line up around the stage.  Consequently, the people who didn't wait at all get the best seats in the house and the people who waited the longest get the worst.  At the Avett Brothers concert, I talked to a husband and wife who camped out since 8am to get close to the stage and ended up in the back because they were made to fill up the first half of the GA section.  Terrible planning.
