It's amazing how much stuff is transported across the country hidden in plain sight. When I lived in Nebraska there was an issue where an Govt Contractor in a unmarked semi truck hauling nukes to Washington State flipped over. Looked like a regular Semi and was traveling back roads to be discrete and avoid major population centers. A local reported the overturned semi to the Sheriff's office who sent a squad to investigate. The Semi Driver wouldn't allow the Deputy to approach the truck and held him off with a M-16. Of course they thought they were dealing with a nut case until the Military showed up to take over.
