Even the best lock doesn't prevent someone from slashing your luggage, nor from stealing it, but it foils the opportunist, the sneak thief who has only a few seconds to get inside and doesn't want you to know he's been there. Locks signal an observer that you're aware of his presence. Like any wolf, he'll prey on the weakest in the flock-and that won't be you. Luggage Tags Buy sturdy luggage tags, perhaps ones that have a leather flap to hide the name and address from prying eyes. Your address goes on the back to prevent passersby from knowing where your empty home is.
Some travelers use an office address or a friend's name and address.
Don't forget to include your country with the rest of the address. Since baggage handling can detach any luggage tag, tape your name, address, and a friend's telephone number, to the inside of your luggage. I strongly recommend also tagging, or otherwise marking, your camera, daypack, and anything else from which you may become separated. When a lost bag is located, it is sent to the address on the tag. If that's your home, that might not be your first choice when you're in the middle of a trip.
