groups would be nice, but one thing to remember if it realy does go bad, is its hard to truly trust anyone. fact is survival takes over and even close friends will back stab you if they feel it is absolutely necessary to do so. id need a pretty long lasting relationship, theyd have to be close by, and have to be completely supplied. think about it. say you keep a saw for cutting wood. you tell the guy in your group for months to get a saw because he may need it. he refuses. then it all goes bad and youve got the saw and you both need it, how long does it take before things get ugly between you two?
