Correction: jaded southern Cali folks.
I've not been to this venue before and thanks to the pic Jessica posted I'm tempted to try for something between the lawn and the pit since it seems you can get a good view from the seats.
$100+ isn't such a bad price considering that, on that line-up, I listen to Muse, Florence, Panic! and Death Cab with semi-regularity. So for just those 4, it breaks down to about $25 per act. Plus there's the other bands that I like the couple songs of theirs that get played on Live 105.3, so the rest of the cost is getting to hear those songs (and get exposed to more).
