(except when disarmed by airlines or cruiselines)
They've never managed to disarm me. I was at a conference on terrorism a few weeks ago. Several of us were having a casual conversation during a break with an Israeli counterterrorism expert. We'd been joking about (shaking our heads at) the total incompetency of US airlines and the TSA. Somebody mentioned the old ladies with their manicure scissors and plastic knitting needles. At that point I grinned and reached into my coat pocket to pull out one of the stainless steel ball-point pens that I routinely carry on board; three or four people (including the Israeli) nodded and pulled one from their own pockets. Sometimes I even decide that my knee's giving me trouble again and bring my cane with me. http://www.canemasters.com/
