Just thought I'd post a bit of info on this matter, since some folks have insisted that it's unlawful, while others say there are no such restrictions. The law can be viewed here: http://www.gunlawnews.org/FOPA-86.html In a nutshell, as long as you are travelling between states where your ownership of a particular firearm is legal, then you can keep them in the trunk of your vehicle, unloaded, and locked, and not have to worry about prosecution. This assumes, of course, that you are not going to stop in a prohibited state for a significant period of time. Therefore, stopping for food / gas is fine, but stopping there for a vacation is not allowed. No state or city law may pre-empt this, as this was part of the "Safe Passage" act. Anyone who tells you that you can't pass through their town because they forbid your lawfully owned firearms is either ignorant of the law, or lying through his tooth. Thus, if I had my handgun collection in the trunk of my car, locked away, and unloaded, and were driving from Florida to Maine, and passed through Washington D.C. and New York City (places where handguns are all but forbidden), it would be perfectly legal to do so, as long as I were simply passing through those cities. There is no need to re-route your journey for legal reasons. If you want to boycott those cities for personal reasons, though, that's your choice.
