The replies so far all seem pretty good. Please be aware that even though you mentioned certain states, you never can be sure if you might be going thru some other state or, even in some states, a town, city, or county that has stricter rules than the state (ie NYC vs NY). Unless you have a real pressing reason for bringing your gun along on a trip (and the locked unloaded gun in the trunk and separate ammo container is as good as it can get), you are better off not bringing the gun then researching your options and finding out you are wrong or have misinterpreted state law should you be put in a police situation.
