Phil, from what I understand from Hans response: as long as those firearms are safe and sound in the airlines or customs hands you can go have a look around.
I will require a permit for myself due to the requirements and my situation.
For the cost of this permit, why not. To each his own.
No doubt. My only concern was if you get a permit and you're not in possession of your firearm and you go through customs, what then? Shouldn't be an issue if you've got all your flight info and they can track down through the airlines that they still have it. But that could be a mess for a bit.
