Last week I left my Macbook and iPad on the conveyor belt at Logan. I was asked over for a bag search, so I put my shoes back on, filled my pockets again, and went over. Ten minute discussion over some duty free I had, which I ended up surrendering. Plane deadline getting close, and I just forgot to pick up computers (yeah, I know).
Discovered they were missing from my briefcase when I got to Maine, in a town with no cell phone access. Eventually got their number, called, got called back, called again with a detailed description. Got called back again 'we have located your items, please call again to make arrangements'.
Later in the week, back through Boston, picked them up from (as stated above) State Police building. Very friendly guy. Showed ID, signed form, walked away with items. Parked illegally in their carpark. People on phone also very helpful, so I'm quite impressed. As I am with getting TSAPre most flights, even though I'm not a US resident.
