It is lways good to have your passport with you at all times.

Imagine a situation when, God Forbid, mass evacuation is necessary. Such as the time of the conflict in southern Lebanon as well as the two Gulf wars.

Now let say (again hopefully it will never come to this) the tension between Iran and Israel and/or the west get out of control. Then , you would certainly want to have your passport handy.....
