David, I'm at Detroit airport waiting for my flight to London in a cyber cafe near my gate.... In Minneapolis, I asked for a hand search of 30 rolls of film. Each roll of film got the residue swab!!! But the TSA agent was really helpful. My camera bag got some major scrutiny though. Another TSA agent wanted to look at my hasselblad. My tripod was checked with my luggage and fingers crossed nothing goes awry! I'm on my 3rd 22oz Sam adams. :-)
