The first Woodstock had it's problems (attendees burned down the food stands then too). Abbie Hoffman blackmailed the promoters into giving him $10,000 and a free table so as not to disrupt the event. Even then Pete Townsend had to whack Abbie with his guitar when Abbie tried to take the microphone during the Who's 3am performance.
The eco-generation left an environmental nightmare behind.
Altamont and the Isle of Wight festivals came with their own problems.
true... you are right. The last one was a pure disaster and I think that's the last of Woodstock-wannabes.
