Its basically a giant art exhibit/party in the middle of the Nevada desert. In the sig is a pic of my girl and I on the left, behind us(its difficult to see)is an aerial shot of Burning Man. Next to us is the "temple" its a structure built every year, its often used to remember those lost the prior year and is burned on the final day. On the extreme right is the Blue Man which is just an awesome piece of art. Then of course my AV is the "Burning Man" himself
Check it out for yourself.
Until you go, you'll never know.
