I was on my way to Atlanta 2 weekends ago with some of my students and went through MIA. One of the LOVELY, overworked TSA screeners decided to check out myTamrac backback out of the carry on scanner. As I was saying "please be careful with the bag, my years savings are tied up in there" I saw my bag drop 12"and then heard the clunk. I got a nice apology and a quick search after a system check, unfortuanately one of my favorite zooms took a shot that I didn't pick up on till later. The 18-70 Nikon lens was on the D70 and my 28-70/2.8 was in the bag next to it. The 28-70 is no longer capable of zooming without holding it with some outward pressure. The gears are all out of whack. Unfortunately I didn't find that out till this past weekend.
The moral of the story is simple, beware of overworked TSA workers during the busy holiday season and keep a really good eye on your toys. The lens is on its way out for a factory touch up. I sure hope its home in time for Christmas.
