Watching the Colony series , I started thinking about GROUPS of people getting together to survive. In that series some groups shletered in place ( mainly the Colonists ) while other groups were mobile.

Question got me that single survivors maybe more quiet and stealthy but more likely than not you would need a group. As they say : there is safety in numbers. So, what are the elements in deciding what group of people to join .. how big a group, what kind of a group, and how do you get to join a group.

The mere thinking of it makes me nervous. I know that ideally you should join a group BEFORE SHTF. But let's say the world went upside down , you lost your home and whole neighborhood. Your neghbors were scattered, and no one knows who is where. And you found yourself alone or with your immediate family (spouse and kids)... and needed security in numbers.
