i go to the U S 5 or 6 times a year it is a pain taking shoes ,belt,hat,watch,ect ect but if it makes travelling 1% more safe its has to be worth doing .
if i keep any metal on me at all i send the screening machine mad so i remove all into the tray. last year in newark i left my wedding ring in the corner of a tray i went back 30 seconds later it was gone it vanished into some security guards pocket assho1e
