BigDayOut

The Big Day Out is a music festival in Australia. (wikipedia:Big Day Out)

It gets pretty crowded, especially in front of the main stage: http://www.travelblog.org/Photos/3347514

In fact, some people have gone so far as to compare the whole Big Day Out experience to Auschwitz, primarily due to the 'D':

“	Although my tour of Auschwitz gave me a small, visual understanding of what it would have been like for my ancestors to be herded into a camp of misery and death, it was not until my experience with the d-barrier that I was offered a practical re-enactment	”
