The masses started arriving yesterday. Gates opened at noon, and ‘Roo-goers were ready. At left is the “before” shot — the open grassy field (once home to cows and cow pies) that will soon be just a field of dirt covered in dirt-covered people and dirt-covered trash.

Unless Clean Vibes has something to do with it, that is. They’re the expert trash-picker-uppers I mentioned last year. And if what I saw yesterday is any indication, they’re back in full force.

Trash cans are covered with recycling messages, and “green info” sites have popped up all over the (super massive) Bonnaroo grounds. I even saw a large truck covered with a sign saying “Recycling Is Sexy.” Yeah, it is. (There was a stripper on the Solar Stage to prove it!)

Grist thanks its sponsors. Become one.

More “sexy” news to come.
