Trust no one with your preps and plans until you get to know them good.
Meeting new people as a possible friends or members of your group for the moment when SHTF should actually should not start from “are you prepper” kind of discussion.
It does not mean anything for you if your neighbours saying they are preppers You still do not know what kind of person he or she is.
And you could on that way just “blow” your plans about preps to wrong person.
I would start slowly with regular “get to know your neighbours” trough local community activities.
After that start with joining activities with more sense like getting to know people who are into things like hunting trapping, canning, fishing, hiking, gardening… activities where you will eventually find like minded people.
And keep in mind just because you might be good person that does not means everybody else is good person.
So “let’s prep together” or ” I am prepper” should come at the end.
