I have done it a number of times, at political rallies at the state capital (Arizona) and posted the articles here on THR. It has been gratifying to see the attitude change, from 5 years ago when the young black man did it at an protest during the Obama campaign, as I recall, to now dozens of openly armed people protesting at the State capital. Lots of support for it, but we have AZCDL in Arizona, which is one of the finest local groups to work on restoring the right to bear arms in the nation. They were the ones mostly responsible for moving us to constitutional carry here. I am a life member.
