I could walk naked through the detectors and still manage to set them off. I just returned from a cross country trip wearing a USAK Semi and had zero problems. I let the TSA agent know I had buckles holding stuff on and she had me walk through. Alarm went off and I went over the the wanding area. Now, the hometown airport TSA lady I think was messing with a male co-worker. As I was putting the sporran, computers, brief case, shoes, belt and coat through the scanner, I caught her out of the corner of my eye saying to the x-ray operator, "Oh, I love that look". Then, she gets a really sly grin when I told her I know I'll set off the alarm as she calls for male assistance. This guy was clueless and they knew it; finally I said, "Man, its just a kilt. Wand as normal" while she's laughing at him. Coming back through the airport on the other end was so uneventful as to be a yawn; in fact as I was putting my shoes and sporran back on, I commented more to myself that at least I remember to not wear a SD. The TSA agent doing a test next to me said, "Yeah, some don't". I said I'll bet that caused a lot of excitement. He said only the first time it happened.

The moral of the story is that, for me at least, there is no more or less hassle going through the checkpoints kilted and I'm much more comfortable.
