I've resigned myself to the fact that government will restrict my movements or freedom if I don't fully comply with their insanity when I travel. Sadly, it means that I usually go without my creature comforts, or check my bag. I'm multi state legal to carry a firearm, so it usually comes with, but it is a hassle. As far as carry on, as others have said, I pack light. No liquids or metal bits, and in the front zipper pouch of my bag, I carry my ear buds, GPS, card holder, watch and power cords in a big zip lock bag, along with my ipad mini. That reduces my load out to basically 3 items to remove. The bag of stuff, phone and ipad, theWhen I hit the block, I unzip and toss those items into the bin. I wear a wedding ring, and also a gold crucifix on a chain around my neck. Those things never come off.
As a side note / story, I had a late afternoon flight a few years back, and decidid I would reload a couple hundred rounds of .45 before I hit the road to kill some time. When I hit the checkpoint, who do you think they picked at random to do an explosives check on? SUGGESTION...don't handle any explosive materials before flying...Trust me.
