Arizona, Vermont, Alaska (They do not issue permits, but rather each person is PERMITTED BY DEFAULT). Which is the way it should be.
AK and AZ issue permits for reciprocity. They're generally not needed in state (I think AZ still has a clause where you need it for bars). Vermont residents just get screwed as far as reciprocity goes. They also wouldn't allow felons to carry but minor details like that apparently don't matter when constructing a survey. I thought the survey stunk and picked on the first response in it.
