Someone said it's about confidence. To me that is 90% of it. The other 10% is where it's located at on your body.
And also just your general appearance. I have no doubt that security consciously or subconsciously profiles people as they come in. So if you're a fairly clean cut looking, sober, middle-aged white guy -- chances are pretty slim that they are going to suspect you of anything.
That’s a big part, confidant and non-threatening, always polite and complimentary
And smile a lot. You will set it off. Last night I walked through the detectors at a
show completely rigged up, set it off, smiled and laughed! They waved me right in
without a wanding or pat down
