Once again, I experienced zero problems with the TSA.

46. I've never had an issue other than the occasional

moody official and hey, who isn't moody once in a while. I carry a whole array of piano tech tools bound together in a tied canvas roll in my carry ons. Talking about suspicious, there are several items that could be very dangerous weapons, but I declare them on arrival, they scan them and let them go through. Only once did they look at them. I think they must know what piano tuning tools look like.
I was pulled aside one time for what seemed no understandable reason and they were looking concerned. They scanned the outside of my bags for bomb making material twice. Then they took me away from the public and asked questions about my travel and if I had anything unusual under my clothing. I happened to be wearing two neoprene knee supports. The guy asked to see them so as I started to pull up my pant legs he stood back, looked away and sort of winced then asked me if I could take them off. Afterward, he exhaled pretty strongly and said it would be helpful if I declared any neoprene supports. I asked why but he didn't say. Later I found out that's how some suicide bombers carry their stuff, neoprene with straps and velcro. He was very reasonable during the exchange. I don’t wear knee supports on planes anymore.
JFTR, I'm in my 60s, white, male and somewhat bald so I don't think profiling has anything to do with it.
