In AZ we need a permit for concealed carry, but anyone who can own a gun can carry openly. I see it at least once a week.
Whenever I am in a checkout line behind some guy wearing a pistol on his belt, though, I think about how easy it would be to just hit him with a bottle and take the weapon. That's why I stick with CCW unless I am going to the range.
I'd prefer concealed or open. Should be your choice I think, and probably have licenses for both.. One license to do either at your discretion.
Then eventually phase out licensing at all.
