How interesting as my hubby got stop at airport to for same reason, we were like omg what explosives .. we never knew why. He works on carsAnother thing about cloths for me, is that I only need one pair of decent cloths to go out for dinner, if needed, while traveling for business.
Since my work puts me around classic (AKA: old) cars, I'm going to smell like old car within fifteen minutes after driving at a job side. I typically get up, toss on yesterday's clothes, and shower when I get back to the hotel. My dirty clothes have to go in plastic bags to get packed for the trip home.
To put this into perspective, I once got randomly stopped by TSA (airport security), and they swabbed me down, and I tested positive for explosives. Really got the attention of a lot of people around me. About 45 minutes later, an explosives expert cleared me to go. Unburned hydrocarbons can test as explosives. Go figure. I had time before my flight to down a few Jack and Cokes.
I do have to give props to all the TSA agents involved. They were very professional, and very polite.
