There is an important policy change this year that could have an impact on anyone sending equipment or supplies to the playa in another vehicle.
The stowaway policy is changing. In the past, there were lectures, warnings, and time spent in the penalty box at the gate. This year, any vehicle found to have a stowaway on board will have tickets confiscated from ALL passengers, the vehicle will be denied entry (so a campmate/friend in another vehicle in your caravan can't drive to your campsite to unload), and everyone on board will be sent home.
Make sure that whoever is going to be hauling that shade structure/art car/tent/food/sculpture/dome/bar for you understands that, and is dependable enough not to put all your shit in jeopardy by being dumb enough to try and sneak someone onto the playa. Drivers, make sure all your passengers either have tickets in hand or will call info before you head to BRC.
It's a harsh policy, but a necessary one IMO. With no tickets at the gate, anyone turned away would either end up lingering and trying to sneak across under cover of darkness (sure it'd be fun for the perimeter guys), they'd be that negative stereotype dirty hippy vagrant hanging around Gerlach all week, or they'd be that person that potentially died of exposure/dehydration trying to walk home in the desert.
