Sounds like it's gonna be good one, report back!
The best part we had was In July the day after we moved into our house (7 bedroom rented with friends). Anyway, we'd been planning it for a couple of months, and word had got out. At full swing, there were more than 100 people inside, on the road and in the garden, including bouncers from our regular club, and friends of friends of friends.
We had three bands playing in the kitchen, a boxing ring in the garden (well not a ring, basically a pair of gloves - and the garden is not really a garden, more flattened rubble). The boxing went well, everyone was so wasted that they just went all out against each other, and i ended up breaking my thumb on my mates jaw after he floored me. We don't do keg parties over here, so everyone brought there own - crates, spirits, wine you name it. Although i don't do em myself, there were a shitload of drugs going round and my housemate answered the door to a copper holding a box full of different substances. Well the coppers came the first time to break up a fight on the street, and asked us to try to keep people inside and not on the main road. Well we couldn't, so another 6 cars and a riot van turned up. Nothing happened in the end, but we pissed off our new neighbours, who went on to send court orders about noise, drinking etc etc for the next few months.
The house was pretty fucked after that, and we have definatley lost our deposit, but fuck it it was worth it.
