It was very fascinating to visit White Sands, also to go there, I took the way from Carlsbad Caverns. The feeling that I remember was the very warm surface but if I just dug some decimeters down, it was rather cold. Perhaps there must be some more to show and I also remember that it was some kind of military area(1994) and the military could close it down when they needed. Perhaps not so good in a HHS.
