I get extra explosives screening every time I fly. A medical device I carry with me must have been the subject of some special alert, it has gone from no problem, to remove it like a computer for x-rays, to do an explosives swab every time. I must certainly remember never to touch the carry bag after shooting. God help me if it turns up positive sometime, i will be in screening forever.
I had a friend at work who claimed he was getting picked every time for extra search as we boarded the plane, back when they did that more often. So the next flight we are standing in line and he tells me this, so I like a fool say lets switch places in line. Of course I get the extra search this time.
