This is Burning Man
The history of Burning Man has always been a complex entity that has survived, nay, mutated over the years. And because of this, it has grown rapidly since its humble beginnings of a simple gathering on a beach.
The infographic poster shows only a small portion of what Burning Man is. By no means do mere numbers even begin to show a complete picture, as that is a history of stories, experiences, and individual tales.
Alas, data points for 2010 are obviously not included at this time. When the information is announced, that information will be updated.
Yeah, you're probably going to want to embiggen this: www.flickr.com/photos/xmasons/4841339241/sizes/o/in/photo...
