How can you think of blaming anyone? It's a free fucking concert with 20 bands, at least half of which could get 20 bucks a ticket on their own tour. Of course come scalpers got their hands on some, why is that so fucking surprising? I'm so sick of the same old whine-fest every time a show sells out.
There were only 38,000 tickets people. And for the most part, they were free. Of course they were going to be gone in an instant.
Sorry you didn't get your tickets, but enough with the crying already. Either pony up and get some on the secondary market, take your chances at the venue or hope you get lucky and someone give you their extra. Otherwise, enough with the crying already.
