I agree 100%. Carrying is not a joke, and the less confusion about what's real or not, the better. I put my J-frame in my pocket when my daughter and I walked around last night. There were a couple of times when guys answering the door acted a little weird (as in "Are you out all alone tonight?") until they looked up and saw me observing from the sidewalk or the street.
I agree too but... the flip side of that. Do you really know who's ringing your door bell or knocking? We don't get many kids trick or treating in my suburb with large lots. But a couple of years ago there were older teens doing the trick or treat thing. Hate to be caught off guard opening the door, iffin' you know what I mean.
