It's part of a three-day music festival - like Warped Tour, so it's not like we'd only be seeing Halestorm.
I checked and there's actually an awesome lineup. Halestorm, The Used, Godsmack, Five Finger Death Punch - lots of alternative rock bands.
As for ticket prices, VIP tickets are crazy expensive. General Admission tickets for a single-day pass on Level 2 seating are 85.00. And then you need money for food, merch/souvenirs and other things. VIP passes don't include any meet-and-greets so I'm assuming that might be a 'merch tent at your own discretion' type thing.
I'm wondering if Warped Tour's lineup will be any good, and if they're going to have regular "general admission" tickets because 2018 is their 'farewell year'. Right now they're only selling preorder bundles.
