After an amazing week at Burning Man, I now understand why this question is a bit hard to answer. So here is my attempt to do so.
It's where you wait for 7 hours in line to get through the gates.
It's the places you'll go...
...to get a better view...
...and be kissed after climbing a scaffold.
It's swinging around on gymnastic rings wearing a pink tutu.
It's dancing like crazy at sunset.
It's happy hour everyday!
It's riding big bikes.
