I don't recall being offered early entry the year I brought placed theme art. I had it for another reason, so didn't pay attention. We did get a day pass to drive it to our location. They take you out to your spot which is marked with whiskers and a cd, in a golf cart, and then it is up to you to get your piece set up there. We3 did get a day pass to dive to our spot to set up. Didn't use it, we have a bike with a deck.
Art out on the playa is at the mercy of the elements and the participants. Art in camp can be watched and tended. My Home for Wayward Art is in camp. It is nice to have stuff on the backstreets, treasures to find and enjoy.
You can place art on the open playa without placement.
Some sunshine, some dust, a little paint and a tutu. Yeah.
