Personally, I don't walk out and check the mail without carrying. Or go out and put a steak on the grill. If I could KNOW when or where I would need it, I wouldn't go there. But because I can't know, it goes on my belt when I dress in the morning and off when I go to bed at night and if there is somewhere during the day that I must go that won't allow it, I find a way to not go there. I spent too many years on the other side of a badge to believe in the basic goodness of my fellow man anymore, and vowed many years ago that my personal safety would NEVER be up to the good graces and decent instincts of strangers. That may sound paranoid or bitter, it's not....I just refuse to be a victim and if the price for that is to pack 23 hours a day, so be it. So to answer the original question, there is nowhere that I feel is inappropriate to carry. It is NOT a proactive measure, it's a REACTIVE one and should I not have to react during that particular visit, nobody ever need know I have it so where's the harm?
