My suitcase was searched both ways to and from Baltimore (from Manchester, NH) and I got a nice little note from the TSA that said, "You know! For the security!". Thankfully nothing was taken, but I was wondering what triggered it. I have to assume it was the x-ray seeing lots of little electronic things. A hair dryer, a battery charger, an i-pod charger, a phone charger... they must all add up to looking suspicious. Or something. On the way back I had a couple wedding gifts and they were still there, thank goodness. Still, I'd be concerned, just as you are.
