different passes, wolf, thing which require a degree of biometric information, you put them into a machine, they beep, then you can walk through various turnstiles. the ones we have for media, we have limits. you can't take cameras in some areas. the cars, that's a whole different world of complication and headaches. you need special ministry interior passes to get on some roads. on top of that, you need extra olympic accreditation to take cars in other arias too. we tried to get near some of the accommodation for athletes and our pass wasn't good enough for that today. so the problem really is when you look at this scene behind me, the way you describe it, you make it sound like organized concentric ring of an onion, almost, you don't get that feeling traveling around that it seems complicated, possibly ramshackle. i'm sure that's the design put in place to make whoever might try to infiltrate it even more confused. >> nick paton walsh in sochi, we'll get back to you.
