Let me ask you this sir, what happens if we go through a state not knowing if they accept our permit and they catch us with a concealed gun? if we are pulled over and hand them our permit are they going to pull us out of our vehicle and take us to jail if we are carrying?
Very good chance you could end up in trouble. As a permit holder, it's your responsibility to to know if where you are going, you can carry. Same thing as being local and carrying in to different businesses, homes, churches, etc. Know before you go.
