The Atacama Desert is one of the driest places on Earth with the average rainfall about 15 mm (0.6 in) a year. Clearly, if you hate clouds, this the place for you. Always losing umbrellas? No worries here. If you have plant allergies, this is the place for you especially in the places where nothing ever grows. Want to practice being on Mars? You can do it here like NASA does. If you are one of those people always saying "It's a dry heat", you belong here.
