I probably should just let this slide but since someone else mentioned it... You could substitute "seat belt" for gun and the meaning would be the same. Just as you're just as likely to need a seat belt on a short drive as a long one (per mile driven at least) and since you can get injured or killed during a short drive, I would submit it makes sense to consistently wear your seat belts- every time, no exceptions. I buckle up to move my car to the other side of the street. To me the same goes for a sidearm. If I knew for a fact when I would need the gun I'd simply stay home that day! But since robberies and assaults are seldom preceded by written invitation in advance, I tend to carry my sidearm everywhere it's legal and practical to do so.
