Jim, unless you want to learn the real meaning of deep cavity search...I suggest you don't try to cross the border in that frame of mind while travelling with guns...

I can drive virtually anyplace in this Country including the Peoples Republic of California with a gun in my vehicle no questions asked.
BTW: Does the US Border Patrol insist you have paperwork for your firearms to cross from Canada to the United States? I don't know the answer so that's why I'm asking.
I tend to avoid going anyplace where I can't legally carry a gun and think I might need one and that certainly includes Mexico these days. We used to vacation in Rocky Point but stopped several years ago due to the violence in Mexico today.
