Legendary music fest Bonnaroo urges fans to go green

What do you get when 80,000 blissed-out music fans spend four days in the Tennessee sun? Besides sunburns in inconvenient places, that is. You get trash: 600 tons of it. And you get a captive crowd, which makes it a fine time to offer words of eco-wisdom. Organizers of this year’s Bonnaroo Music & Arts Festival ramped up the green, using biodiesel-powered generators, hiring an army of recyclers, inviting artists to perform on a solar-powered stage, and more. Sarah van Schagen reports from the scene.
