Where are you coming from? There are various caravans heading up that direction on Thursday and Friday, you can catch one of those if you want.  If you look at the Caravan thread it'll show who the coordinators are.  For instance, I'm the coordinator for the East Bay for Thursday...

The registration includes Friday and Saturday night camping fee I believe, and the big dinner is Saturday evening.

The only thing that is really planned for the weekend is the Saturday evening dinner and raffle.  Everything else is a "get to know everyone you can and wheel" weekend.

We have a big group heading in early Friday morning, I wanna say we'll be on the trail by 9 but with a group our size, it's hard to say.  Read the caravan thread and it'll say what days some of the groups are goin in
