just try what i told you anon. the trick is to find a home that is truly "abandoned". they exist. in every city. now bear in mind. you will be broken into. so dont leave anythign of value there, or stash it really good. its best if you can have a "squat mate". two people are better then one, but three is a crowd. you both need to keep everythign on the down low. try to come and go after dark. no loud parties. no cops.  if you let a bunch of people into your sqaut, they will fuck it up. just one other dude, who understands how to keep a low profile.
