I haven't checked the link, but this isn't anything new. Way back in the days of MUSE (Musicians United for Safe Energy), there have been festivals and tours that use these sorts of set ups. Farm Aid I think used one for awhile. All of Bonnie Raitt's tour buses & trucks use 'the French Fry' power.

But the point that the attendees aren't doing it green is significant. Personally, I think the time has come to draw these huge events off the list of 'good things to do for entertainment'.

But what do I know? They just opened one of those behemoth movie theatre parks in our neighborhood with what, 800 or so screens. Think of the cost of heating and cooling those sorts of venues!!!

It is criminal, I tell you. Criminal!
