Secret Base Dulce, New Mexico, USA
Not far from the Colorado border, in northern New Mexico, is the small town of Dulce, with a population of just 2,600 (mostly Navajo Indians).
There is a theory that under this place is an entire US underground military base, where incredible experiments are being conducted and the latest technologies are being developed.
Conspiracy theorists say this underground complex is home to hybrids of humans and animals, humans and aliens, and that this is where you can see the most advanced devices on the planet. The authorities, course, deny everything.
