snorrtt!!** oh god it's an experience! (if you like Footballers Wives of course)
there are sometimes a few parties out by GUildford way.. but I can't remember any of the names of the systems..
If you want to meet a great bunch of people, they meet by the river out side the Britannic (used to be Scruffy Murphies) on a Thursday evening for poi and staff practise.. not sure if you are into that sort of thing.. but they've got an ear to the beat of the underground so should be able to point you in the right direction..
