Some people fine abandoned places very creepy while others regard them as extremely fascinating. I align myself with the latter camp.
With the few derelict and discarded locations we've visited, the underlying motive has never been about exceeding the amount of vandalism the site might have already been subjected to but rather about being extra curious with respect to the soul of the place and the stories the dilapidated walls tell when as we explore.
We've always deemed it important to show reverence for what's been left behind and if exploring abandoned places happens to entice you as well, I'll leave you with this rule of thumb I read somewhere regarding this leisure pursuit: “Don’t break your way in. Don’t take anything, except photos. And don’t leave anything except footprints.”
We didn't come across any "No Trespassing" signs but as we excited the buildings, we came across a gentleman that told us not to get caught in there because police will 100% arrest anyone with no questions asked.
