This was the reason I posed my upstream question. Unless Chicago is locked down to the point that a gun owner can't even buy a shipping case in the city, it would seem like the common sense thing to do would be to buy a proper shipping container and bring it home via checked baggage. Than, the next time he flew out of ATL, he could just wink at the clerks. (Winking, or course, would cause him to earn some SPOTNik points.)

On the other hand, in Chicago, he could probably sell it on any street corner.
