I'm leaving Wednesday now as well! I'll be in Spokane Wednesday night, and then up early to do some last minute shopping, and then hopefully at the gorge by 2-4ish. I'm not really sure what time is best to get there.. so I'm just going to guess.
Once inside, the camping gear goes up, and the booze comes out.
Souly, according to the gorge site the campground won't open until 5:00pm on Thursday, so you may want to plan for some tailgating if you arrive at 3, or spend some more time at your friendly local Target (or sleep in a bit on Thursday).
I'm HOPING that most people didn't take Thursday off work and plan on driving in later that night or even Friday morning. We're showing up right at 5 so hopefully there won't be a massive line of cars getting there at that time.
I think the fact that shows don't start until later on Friday will ease the line situation quite a bit. In years past, almost everyone has arrived between 2pm-12am on Friday. This year they'll have from 5pm Thursday-3pm Friday to show up, and I'd guess just as many people will come Friday as Thursday. Fingers crossed.
Anyway I'm in Wild Horse but if I get a chance to come by on Thursday night I definitely will.
