I am not sure about your last statement. The one about neighbors. I say conceal your supplies, they will get suspicious of you if you talk to them through a tiny slit in your door and refuse to let them enter. The commies are questioning them and they will rat out the "freak". It doesn't matter if they know anything or not, they will think you are weird and be glad to get rid of you. This is like you said before, don't stand out from the herd. If you act too secretive they will become curious. The most important thing to remember is you aren't in the militia, you are just a normal civilian with nothing to hide and nobody needs to take a second look.
