. If that means hiding your weapons from the authorities to keep them then so be it.
that's everybody's first reaction, of course. But what complicates this is the madatory evacuation. They come to your house, say you have to come with them and you can't bring your guns. What are you supposed to do? Sure, you can hide them in your home, but then you get shipped off to some shelter in a different city with no protection and probably no means to buy more. A lot of good your guns do you hundreds of miles away in a condemned city.
Can't answer that one except to say your guns will be where you left them when you get back. If you evacuate voluntarily you can put one in the glove box and recover the rest when you get back, assuming you have a place left to go back to.
