Salar de Uyuni
The salt flats of Bolivia look aboslutely surreal on the right day. The flats extend for 4,000 square miles, and when it rains, it the ground looks like endless sky.
Roswell, New Mexico
Roswell, New Mexico is another popular alien site. A UFO supposedly crashed there in 1947 after a ranch worker found remains of what was thought to be an aircraft. The city has become a total tourist spot and is literally outer space themed.
