after reading this i can conclude you should instead be paid to go there
the price of the ticket goes towards maintaining the toilets, wetting down the roads, ranger services, medical supplies and art installations. it's like temporary city kind of self-governed by burners and the price is high to deter people from coming and to make bank (since it's hosted on federal land and that's not cheap)
either way it is very expensive at over $50 a day.
