Don't tell me...

[Tigs]

I will be on my own with my fella and 3 kids, once the sheeple have gone...any advice on how to find a group of nice preppers who would take us into their group? Do I walk around with a white hanky on a stick? lol.
I will have uses, I am a hard grafter, not afraid of getting dirty. I can help raise the animals, p[lant and harvest crops, go hunting.
How would you advance towards a group of hopefully friendly folk?
Are there any tell tale signs that a group might be baddies?

other than prearranging to meet up with people from here or other sites the only way to form a safe group i guess would be with people you knew and trusted before the fall (non preppers) , or to watch a group over a period of time to see how they act and interact the problem with that is that when you approach them they might not trust you!!
