Well I do professional sound, so I know my speakers. And I have a huge group of my friends who've done it for a long time, more than a decade - and they keep trying to get me to go, but, its never a good time for me, that's the opening season stuff for me and I ain't never had those two weeks open, if they would do it in January (which would have other advantages, I do so try to stay out of the Great Western Deserts in the summer). Anyway, I've helped them pack and waved good-bye, and helped them unpack and clean that stuff. And I've done gigs cleaning - like horse trough of water, and brushes, the miles and miles of audio and video cable that gets sent up there. It's very dirty. But anyway that cloth just screams Black Rock like tie-dye sox yell "Jerrrrrrrrrrrrrrrrrrrry."
