Gen mentioned it's $5 a head, now, all of that has to go to my parents, but I'm willing to skim some off the top for some meat. However, can I please stress how important it is that this be covered, if you can't afford the $5 then find someone to cover it for you, or donate something to me, otherwise I'll end up covering it myself, and I can't afford to do that

Don't want to sound like a prick, just outlining the rules
Also, about the music, I think just a decent stereo will be fine, as there are some neighbours close by, so I think getting decks etc. may be a little over the top...
If you guys are interested in running a full on bush doof, I have other property that can be used and we can maybe work something out for next summer. Just have a chat to me if you're interested.
