This Spring I was in DeGaul. The line wasn't too long so I asked the 3 guards to hand-inspect my Nikon, since it had 3200P in it.
I waited on the side for the policeman to show up. He basically hefted the thing and was about to okay it, when I offered to take the lens off so at leased there'd be a semblence of a real exam.
The policeman okays it, tells the X-ray guy. I walk through the metal-detector and wait with my hand out for the guy to pass my Nikon to me.
Then I see my camera rolling out on the conveyor belt.
Ugh. Well, that was 20mins for nothing.
I usually use a lead bag. I've never had anything fog on me. Neither did this film, fortunately.
