Be aware that other count rise are far more stringent than the U.S. When it comes to airline restrictions!, as much as it is a pain(and I am very vocal when angry)things such as scissors, nail clippers, matches, lighters and knitting needles are a big NO. Can't amuse myself except music, reading and computer games. Only thing that will make it thru are the small cutters and needlepoint. Mexiconis particularly stringent. Freedom from worry means a price and much as I hate it, it is a price I'm willing to pay (other than that nasty e ray machine gizmo that sees everything!).
