On the other hand, I had six Soviet aluminum cases covered in Cyrillic in my car while I was working on a film in 2006. Inside was a Kinor 35H system, but from the outside it looked like old Soviet military surplus. In fact, while flying into the country I was told by Customs on one occasion that the metal tripod tube is very similar to a tube used to pack Soviet RPGs. Anyway, I crossed over the Canadian border on my way to both Montreal and Vancouver and passed back into the states. During all four crossings my stop at the border took all of 30 seconds. Nobody ever asked me what the Soviet road cases were all about or if I was planning to blow up any government buildings or shoot any foreign nationals.
Of course, I tried to take a snapshot of the White House once through the bars in the fence and as soon as my lens went between the bars a guy in uniform took an aggressive posture and parked his nose about an inch from my right cheek. So it kinda depends on where you're trying to work. ;-)
