In all my years of doing this, only one location ever gave me the creeps. A story about, that I posted on another forum is below...
Follow the link at the bottom to see a Google satellite image of a vacant lot upon once stood the only site that ever made me feel truly nervous.
This started as a looting mission for materials for a mad science project. The building was originally a country club, but later became the NY Tech Thermodynamics Research Facility and also housed a laboratory supply company. We had to force our way in, which we thought immediately was a good sign that the site had not been previously looted.
Inside we found a cavernous building. About 4 levels of open halls, a couple of grand stair cases, lots of small rooms, a multi-room roof top cupola and all of it covered with Satanic grafs to the point that this could be considered the Satanic equivalent of St. Peter's Basilica.
We kind of realized that it must have taken a considerable amount of time for this huge quantity of grafs to get painted and many of them appeared to be by skilled artists. With this in mind, I was starting to feel a little nervous as to what the keepers of this Satanic nightmare world would think should they happen to find us desecrating their private sanctuary.
Even still, we completely searched the building and didn't find a bit of hand-carry loot, but there was some large items outside worthy of retrieving, but no one other than myself was willing to return.
