Most states have reciprocal agreements. There is a book one can buy that lists the nuances of each state's individual laws and procedures. If you intend to travel and want to remain legal while carrying concealed, I highly recommend purchasing the book and making absolutely sure what you can and cannot do in each state. Hell, keep the book with you, if you are pulled over and have the book, chances are a reasonable law enforcement officer would show discretion and leniency if you showed them that you did what was shown to be the law. They likely would issue a warning and send you on your way. That is if it were a benign thing, like a traffic stop for a tail light out or something. If you're running dope or something, I wouldn't hold your breath.
