If you don’t seriously outnumber them do not allow them free access to your supplies. They may decide they want everything and kill you to get it.
See my reply #54. I and my other neighbors can handle the dad, easily. It’s the crazy adult daughters and their boyfriends that are of concern. Tattooed criminal looking types. One time a drug-crazed boyfriend of one daughter was raising a ruckus at 3 am, I went out on my deck overlooking their back yard and yelled at him to cut it out or I would call the cops. He got quiet, and pleaded with me not to do so because he just got out of jail. So yeah, I worry about my family if I’m not around to deal with a problem. Both my wife and adult daughter living with us have practiced handling handguns, but I don’t want it to come down to that; I’d rather be the one to deal with it.
Two 'Prepper Rules' here:
#1 OPSEC (be silent about your plans ,resources, never let anyone know all your plans, resupply at night, be clandestine, etc.)
#2 If you can't defend it ,.. you don't own it (intrusion alarms, dog, defensive tools, etc.)
