Onsite camping entry without a vehicle

I’ve read the detailed instructions about the vehicle line-up & lottery procedure for onsite camping, but can’t find any information about what those of us who won’t have a vehicle should do. I’m visiting friends in Boulder before the festival and they have kindly offered to give me a ride up to Lyons on Thursday, so they will be dropping me off with all my camping gear. I’m sure others will be arriving via airport shuttle. How does onsite camping entry work on Thursday if you don’t have a vehicle?

Those without a vehicle will be let in to set up camp at random while cars are being let in, so nobody is in danger of being hit by a car. Just try to stay off the main roads into and out of the ranch.
