The Gorge June 17 - any info appreciated!!

Hey all, in celebration of a few personal victories, I have purchased a ticket from SeatGeek/FanXchange to go see Tool at the Gorge June 17!!! I am a lifelong Tool fan, never has there been a band before or since that I have had such an emotional attachment to...this will be my 7th Tool show but 1st in nearly a decade and I am PUMPED! Anyhow some questions:

1. Have any of you used FanXchange before? What are the chances they sold me a fraudulent ticket? Low right?

2. Any driving tips for me, I am coming from Canada, alone!

3. Hotels are all booked up, so I was thinking I'd just sleep in my car til sunrise, either at the venue or at the Walmart in Wenatchee. Does that sound doable?

4. Anyone else going to this and as psyched as me?!
