i heard that they're not having it at the gorge this year because last year a bunch of dumb shit kids set things on fire...
That's false. Dumb kids set shit on fire there every year and it hasn't stopped them before.
Really, a lot of what's been said in this thread is false.
A lot of the information Kevin has posted on his twitter has openly discredited a lot of the claims: The venue was set at Marymoor because the Gorge was booked. Venue was moved to WR because city of Redmond officials were trying to limit warped (no backpacks, no water bottles, no snacks, no nothing), Marymoor was slated to use the ENTIRE park for Warped and not just a small section, White River will not have seats, White River will happily honor tickets for Marymoor.
