Ah, Hassard Cheratte. The Disneyland of urbexing. Last time I went there, there were at least 10 other people. On a regular week day. Imagine how busy it is on weekends -_-'
I was there on a weekend and we met a group of four photographers, two Teens with a Dog and one guy (who was alone). That was all and I think thats okay. The place is big, so we didn't saw the other people just for a few seconds
