I have a spare GA pass unregistered (went last weekend! it was a blast) that you will have to claim at the grounds. $200, payment will be through paypal for our convenience and protection.
I will send you an email of the receipt, credit card used to purchase the pass, IDs/passport, and the authorization letter with your name on it.
Email me at regie_sy@yahoo.com if you're interested. Need to sell today as I am flying to New York.
