I'll send-out a PM to everyone who's already committed with about a week to go with the address details etc.
Right now (having no idea of the likely weather), I'd suggest you prepare for seriously cold & wet. If the weather is brilliant, that's a bonus! Bring a tent & sleeping gear (it looks like the inside-shed spots have already been taken) & put yourself on the catering list (find it above, cut/paste yourself) so we know who's going to want food at particular times.
Costings are TBA, but factor-in about $20-$30 for food for the whole weekend, $25+ for a cube (Golden Promise ain't cheap!) & $20 if you want a T-shirt.
More to follow...tssht!
Edit: If you want to produce a beer & cube it on my system whilst the big mutha is happening, bring-up some grain (according to your recipe) & a cube.
Actually, I'd recommend everyone bring an extra cube just in case the unexpected happens (ie. stellar efficiency) &/or we end-up doing two mega-brews on the day. Depending on what happens, we might need to have a raffle.....
