"When the news says there is definitely no Ebola at Burning Man, there is ebola at Burning man."
Rain in the desert can bog down even a 4WD. And it tears up the roads making it even harder to get in and out.
Burning Man is sitting on a lake bottom (playa) so all the rain water is collecting there.
I'm not saying the whole thing isn't suspect but the rain would cause major issues for those unprepared to deal with it.
