I just don't see the risks inherent in halloween that would lead me to a much higher state of awareness and armed status.
yes, either a pistol or rifle is moved closer to the door, but that isn't necessarily because I'm afraid for myself. I'm worried about angry drunks, predators hunting children, domestic disputes, and so forth.
I see the risk of trouble on halloween night as being barely higher than normal, and I freely admit that keeping a firearm close at hand smells like paranoia. I actually feel a little silly doing it.
