I haven't personally, but I would without even thinking about it. It's legalanywherein the state (in permitted areas, of course), and if you receive any type of harassment, they'll be breaking the law and you'll have a nice little lawsuit on your hands.
You ever notice that when a baby hurts themselves, the first thing they do is look at you to see how you react? If you gasp and ask them if they're ok, they cry. Ifyou smile and tell them they're fine, they smile and go about their business. If you make a big deal about something, other people are going to make a big deal about it, too.
Just carry safely, and confidently, and you'll be fine.
