Well, here's what happened: At Midway airport in Chicago, I threw the light in the tray along with my watch, sunglasses and wedding band. The security officer glanced in the tray and slid it right back to me. Not even a second look. At Orlando International airport, I put it in the tray, but this time only with my watch (I left my ring on, and my sunglasses were in my bag). I purposely leaned the light against the watch so the clip would face straight up. The movement of the tray caused the light to roll with the clip on the side again. The officer took a quick look at the tray and slid it to me. No one even looked at the light. Actually, I was a little disappointed as I'd hoped for a little conversation about it. So, it's pretty obvious that lights with tritium vials aren't something the airports are looking for. The funny thing is that on the plane coming back home, I went in my carry-on to get my iPod and found 2 BIC lighters in there that I forgot to throw in my checked bag. They easily got through security, even though they are clearly prohibited...
DUQ: My back is fine. My knee is the problem, and always will be. I've been off work since Feb 4, 2008 and will not be going back. After surgery and 11 months of therapy, it's worse than it was before the surgery. Nothing they can/will do about it. Thanks for the concern!
