This is more footage from the Salina Turda Salt Mine in Romania.
I also want to dedicate this video to Adi Rus for his generosity and kindness. I also want to let people know that he is a very intelligent man with a lot of knowledge on many different subjects.

Although I wanted to explain more about these subjects I think the observations speak loader than words.
