In Kentucky you can open carry at 18 With no license or permit anywhere except courthouses and schools, you have to be 21 to have a concealed weapons permit the same as Alaska where no city can pass gun laws that conflict with the states law, even if a place has a sign saying no weapons you can still go in with your weapon but if they ask you to leave you must, you can open carry in your vehicle or any other factory issued storage compartment in your vehicle, you do not have to inform police if you have a weapon on you.
