You've seen the pictures of tents and wigwams dotted all over the arena, and there's something pleasing about the idea of being able to camp right next to the main stage if you can find a space. But this was a free festival - albeit by accident - and it doesn't stay free if you have to pay money for your living accommodation. So, here's some people who found another way that didn't cost anything!
Apparently, sights like this were common. This was a grass hut, built by the people inside it with materials they found on the farmland, and served perfectly well as a base of operations for the weekend. You're not imagining the sign over the door either - grass huts or similar ramshackle constructions substituted for mini shops, which you could visit to buy marijuana or other substances of choice. Never let it be said that hippies weren't creative.
