I live in Fresno and most NOBODY in this dismal demographically challenged town knows what Burning Man is...and I say, don't volunteer information. I am renting a UHaul here and driving to Burning Man. Yes, its an 8 hour drive, but I love road trips and I think thats a good length one. Fresno has an airport...so if anyone wants to fly in here with some gear and rent a Uhaul or other transport, let me know, I can probably give you a ride from airport to whereever (if you arrive before the 29th), or I can at least point you in the right rental direction, or we can caravan to Burning Man, if you like.
When/if they ask where you are going, just say a "group camping trip", no need to mention exactly where...and "I need to transport camping gear". No lie - no foul - no bad karma.

Then clean it up before you return it.
Plus the UHaul is great for sleeping in at night if its cold because it holds the heat from the day, and if you leave the back open, its a great place for a hammock!
