Heheh yeah you do need to be on the ball at most squat parties, especially the bigger ones with lots of rigs. And when a venue is putting on parties week after week they invariably start attracting more and more wankers unfortunately.

There's an art to picking which party to go to... you need to know what the various systems are and so on. If I'm around in London my first choice is generally Malfaiteurs as their parties are generally well-behaved and they have some top DJs.
