Fourth of Juplaya isn't an event. Certainly not a BM event. A lot of people go out there, some burners, probably most not. And unlike BM, and other sanctioned events, there are no services. Camp where you want, bring what you need and take everything out.
There was a strong BLM presence last year. A Ranger came into our camp and was conducting a census. It seemed the most important question was what brought you down there. The off road stuff, ATV's and motorcycles?, the stargazing, love of the desert, then, Burning Man? Real nice guy, hope he got to work BM like he wanted.
Again, this is not a BM event, or an event, really, at all. Just a bunch of folks enjoying the Black Rock Desert in the Summer.
