Replying to Anybody ever worked a music festival?

I've never been tempted to attend a music festival but I hear lots of trustafarians do and also that they typically trash the hell out of the area in which a festival is being held. While this is overall unfortunate, I have also heard that said trustafarians tend to leave behind some pretty sweet camping gear. Wondering if anybody around here has ever been part of a post-music festival clean up and if you get to keep whatever the rich kids leave behind...
