Put your pistol in your suitcase before you get to the airport. When you check in, DO decalare your firearm. I have had to open the gun to show it was empty (not loaded). store ALL your ammo in a separate container. Act like you do it all the time. Better yet, dissassemble your pistol (if an auto) before you pack it in your suitcase. MAKE SURE you have a lock on the case, it looks better. That way when they ask you to show it to the tickect agent, you have to unlock the case to show them a disasssembled pistol. Really, don't screw around with this, as you can wind up sitting around for days while they try to find something that you did wrong.
In PRK the first offense for non-permitted CAN be a misdemernor, but thats not what you will be charged with. For it to be a misdemeanor, you have to NOT know that it was illlegal to carry concealed.
On to the good news: if you are a white, normal guy, the chances that you will ever be searched are so low that you ca really get away with murder here. I grew up in SoCal, and because I never gave the cops lip, or reason to bother with me, I have never had my person or car searched. I got a ticket for an open conatiner once, and they never even looked at anything other than my ID. IF you don't look like a gang member or an illegal alien then you will never get a second look from the PD. They have much better things to do than search upstanding citizens. If on the other hand, you dress like you live in tthe Ghetto, and wear Bling-Bling jewlrey, and speed down the highway in your lowrider, you WILL get stopped and searched. Its usually the nail sticking up that gets hammered.
