The tragedy in Haiti is a stark reminder that bad things can happen to us anywhere, and it's a good idea to always take precautions. One thing that you can do when traveling that can make a difference in the case of an emergency, is to register your trip with the government of your country. You can usually do this online by simply filling out a secure online form with your travel plans and contact information while abroad, and contact information for your family or friends back home. You should also leave an itinerary, including local contact information and expected time and date of return, with a friend or family member.
By registering your trip, you help the embassy or consulate locate you when you might need them the most. Registration is voluntary and costs nothing, but it should be a big part of your travel planning and security.

Whether you're a U.S. citizen, Canadian, or the citizen of another country, find out how to register your trip.
That is an excellent idea and probably of vital importance incase of any emergency.
Great advice. I also scan my passport and email it to myself and someone at home, in case I lose it.
