from what I've heard, on Sunday Jane's Addiction and NIN are co-headlining. this is probably why there's only 7 main stage bands for that day. it would be terrible if NIN weren't allowed to play a full set, they put on one of the absolute best live shows there is.
no, i don't believe the price goes up at all, that's just for concert tickets. if i remember right, regular camping did sell out last year but it was nowhere near as quick as the premium camping went this year. regular camping at wildhorse (almost 300 spots) is nearly sold out, so that may be an indication of how quick the gorge campground spots are going. there's an awful lot more than 300 spots at the main campground though.
after i bought my wildhorse camping pass, they decided to add on that tent trailers are in the same class as RVs and can't be used in car spots. it said nothing about tent trailers in their original FAQ (only cars and RVs) so i'm pretty pissed off. also they have a no refund policy, and the premium campsites at the gorge grounds sold out in like 2 hours. great.
i can't believe they sold out already. i remember seeing people selling premier passes on ebay for like $300 last year. wildhorse is almost completely sold out of RV spots and only has about 50 regular spots left. camping is going very quick.
i too don't understand what KOL have done in the past couple years to warrant a headlining slot at a major festival. their most recent record is decent, but not the kind of thing that catapults a band from middle of the lineup to headliners.
well the first wildhorse shuttle leaves for the gorge 2 hours before the music starts, so i think it's safe to say you'd be at the front of the line if you wanted to arrive that early. people that stay in the premium campground have their own separate line and get early entry, but you'd be among the first people to get through the general line. walking from wildhorse is a bit of a hike, it's 1.4 miles.
