best start becoming honed killers then ay chaps and chappettes!

as for finding nice preppers, done hold ya breath, much much easier said than done, as paul says it'll revert to survival of the fittest, theres no clear cut way to say, this ones a good'un and this one aint, will depend situation to situation, just get your analytical skills good, learn to sense peoples intentions and what they are like

and groups of bad guys, well you should be able to notice from their behavior, any group you even consider contacting spend a while observing them from a distance, and i mean a while too, dont just observe for 2 days and think well, they havent killed no one, must be ok, spend a week or ideally more than that before even considering contact, and be prepared, make it so your doing so under your terms, not theirs, keep an upper hand in every situation, even if it means instructing your children and partner to hide in cover and keep rifles trained on those your contacting, just in case it goes bad, if they make threatening moves to you and you say if they move another inch they'll be shot through the head, self preservation will generally stay their hand xD...especially if a warning shot is fired

anyway theres no clear cut method for any of these things, like the situation the approach is gonna be unique
