Easiest time I have ever had going thru security was when I was carrying a cat.
I dropped my bag off at the scanner and didn't remove my ham handheld radio that was on my belt, my phone in my pocket nor any of the other things in my pockets, I didn't even go thru the scanners.
Security waved me to the side of the scanners and they all gathered around and petted the cat then they proceeded to swab me then they swabbed the cat and then a bunch of cute TSA girls came by asking the cats name and then they all proceeded to pet the cat and make it purr even louder than it was when all this started.
Portland Oregon has some cute TSA girls as does Phoenix Sky harbor.
And that was it for me no stress a bunch of nice people for the first time ever.
I think that you should start a contest to see who takes the backpack with the largest variety of stuff (electronic equipment, test tools, adapters, etc.) through security. Contestants should submit pictures detailing everything they have in their bag. On average I have at least two flights a month (most of them internationally) and I carry a civilian version of pack that Camelbak made for the US military loaded with about 15Kg of stuff. Unfortunately, I don't have room for a cat in my bag, so you should see how much fun I have going through security :)
That's really not a bad idea -- I'm a bit strapped for time at the moment, but sometime in the next week I will show my backpack on a table with everything taken out and detailed ... and I'll capture it in a blog...
...then if others want to do the same, they can send me a photo and associated description and I'll do a series of follow-up blogs ... so maybe we can start with you... :-)
