When we bought our tickets, all that were left were general admission. We assumed that all tickets were the same and we could go wherever. That was not the case; we could only be in the stands. Apparently they sold field tickets, but they were sold out quickly. I still had a good time, but a concert just isn't the same if I'm not in the thick of the crowd. Sitting at a rock/metal concert is just ludicrous.
Also, in addition to crazy fees on the tickets, parking was another$20. There were no lot attendants other than the money collectors and it took us 30 minutes to find somewhere to park.
I'd like to go again, but I don't know if I could afford to, between the cost of the ticket, parking and refreshments. I spent a lot more money than I had originally anticipated.
