Due to the problems we were going through, I had not been able to see the extraordinary publication, today I was able to make a recount with the two publications. The electric train is very useful for the walk through the cave. Very impressive those shots, and I love them because I know they are first hand without retouching to the natural, from 1 to 10 I give you 20 excellent publication, impressive the Russian bridge made by the prisoners has a lot of human value, I imagine it was very hard for them pay part of their sentences in the construction of it, all your shots are excellent I look and admire, true works of art to make a good album of the curiosities of this cave. I thank you for sharing so much beauty, and entertain my eyes with such beautiful wonders, The unimaginable baby dragon was not aware that I would be able to meet anyone in this shot so well framed, greetings @oldtimer
