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 the whole Big Day Out experience to Auschwitz:

“	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, so watch this space. (alternatively, I'd love to hear more thoughts. The 'Discussion' link above is free to use for this and genuine discussion will be respected (spam and abuse will be deleted however)
