I'm liable to post quite a bit about this place, because there was just so much going on, but to start off I'm going to say that it is true, the sky in the desert is special. While we were there, the moon was a regular companion and just demanded to be photographed.

The moon is traditionally known as the female counterpart to the Sun. It is symbolic of receptivity, intuition, illumination and a lot of other qualities as found here. I was so drawn to the moon the whole time I was there, I think I need to investigate that a little further within myself. But that's personal work - not bloggable.
