BigDayOut

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

Here is a page with a photo of the crowds they get in front of the main stage: http://www.travelblog.org/Photos/3347514

For this main stage, they have a crowd control measure called "The D", and some people don't like it: http://serongblog.wordpress.com/2009/05/20/big-day-out/

In fact, some people have gone so far as to compare he whole Big Day Out experience to Auswich

“	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	”

Illuminating the problem

Here is my diagram of the problem with the "D". Comments please

Solution?

I have a possible solution for the D dilemma too. Still being drafted.
