I don't do ~*~craaazyyy~*~ things all the time, but I did go trespassing on abandoned property with some friends a few times. It was a whole complex for the mentally and physically challenged, to serve as their home. There was a small gas station/auto garage, ambulatory, eating hall(s), dormitories, etc. It closed in the 90s. There was a graveyard next to it, and the entire thing was on a hill over looking a prison. Totally safe. I forgot its real name, but we called it Silent Hill. XD There was even a room where the walls were covered in vines. It was empty except for a chair, also covered in vines.

We found out (on a later adventure) that they were trying to fix up/renovate the place for something else. We found the room where the construction people placed all their equipment, including a map. It felt like a video game moment.
