Hershey isn't selling very well either. $35 tickets were added this week, where the previous low was $49.50. Also, a 4 seats @ $30/ea package was added. Tons of radio stations are giving tickets away now. And I'd be on the lookout for prices dropping again. Last year Hershey got desperate to fill seats for Counting Crows/Maroon 5 - Tickets that were over $50 ended up being $10.41. Poison tickets were sold for under $10.
I don't know if they decided on keeping Hershey because it sold more or because it was easier to fit more people in. But Hershey doesn't draw much of an outside crowd. They didn't even sell out The Police, Billy Joel, and Springsteen shows they've had. And there were hundreds of scalpers left with tickets they could't give away still.
