When it comes to concealed-carry permits, not all states are created equal. An article in the Birmingham News explains to Alabama residents where their state-issued permits are valid, and where they shouldn't take their guns.

It also quotes Terry's Meigs Professor of Economics David Mustard, who researches gun control.

Mustard says that concealed-carry reciprocity is "more generous in the south," but that concealed-carry permit reciprocity has its supporters and critics.

"Certainly one of the criticisms is that if I have a right to carry, and that right is articulated in the second amendment, I should have that right in various states and not worry about, 'hey I'm crossing this border or that border,'" Mustard said.
