When SHTF, your license is going to be worthless. Any band will be useful there, not just 11M.

Don't use code when you are setting up a trap for robbers. Say you have too much food and ammo for your family and dont even have weapons or guns for your ammo. Show up real early and see where the good ambush spots are.

The problem is how do you agree on what the code is before you meet?

Food is 2nd priority.

First priority going to use a voice changer, attracting pedos to meet, where they will soon meet their maker.
