Couldn't agree more, Mr. James. I carry openly sometimes, and when I do, my revolver is properly holstered. In my part of the country (northern Nevada), that type of carry rarely attracts any attention, at least not if the person doing it appears sane and responsible. If I had a long gun with me, however, in any circumstances that I can imagine it would stay locked in the car if I had to go into a store. (That, or I would stay with the gun and my husband would go into the store.) Laws are one thing. Respect and courtesy are another thing, at least as important as the first, and are critical to living in a society with other people whose thoughs, habits, and experiences aren't the same as yours and who have no more capacity to read minds than you do.
Besides, as we say in science fiction and fantasy fandom, it's not nice to freak out the mundanes.
