You might not find your bearings at all. Border Patrol finds the bodies of hundreds of migrants in the desert each year, and activists estimate that since 1994, there have been more than 6,000 deaths along the border.
The Arizona group No More Deaths has said the number could be five to 10 times higher, since the desert is so vast.
This impacts every aspect of your trip. If you have a good deal of money, you can travel more safely.
Think about it: with enough money, you're probably more likely to hire a lawyer, try to get a tourist visa, hop on a plane and enter legally.
But most migrants crossing the southwest border illegally are coming to the U.S. looking for work. So the amount of money they have available for the trip north is probably limited.
A coyote will help you cross into the U.S., but can cost thousands of dollars. Still, there's no guarantee the trip will be a success.
