This is an interesting term , especially in this context. Does it refer to the fact that having  of one of these little cards allowed you to literally pass out, - due to over - consumption, lack of sleep or the narcotic effects of listening to Joe Jammer or Donovan for many hours - or does it mean you could leave the festival and then pass out outside the fences , due to the ill affects of all the above , or does it simply mean you could leave and then come back for more punishment  ? After 30 years, who knows ? Probably all of them and a few more I can't think of .
