Yup. They asked me what guns I had in the vehicle. Totally fair. I said none and expected they might want to search the vehicle, which would have been totally fair as well. But they weren't interested in that anymore, they started asking what kind of guns I and my passenger had at home. None, for me again, but my passenger admitted to having some at home 500 miles away. He later said he felt compelled to be honest because he didn't know what databases they might be hooked into. The border guard then began grilling him about the kinds of guns he had, what their purpose was, why he would own them, etc etc. Asshole invasive questions that served no purpose. I think the border guard just saw an opportunity to needle an American for being American. At least they let us through after that. They never searched the car, clearly they didn't have any legitimate concern about anything.
