Im just another young explorer in the area. I have been to 2 different abandoned places recently both being near Hatfield. I visited the abandoned school it Hatfield (forgot the name) and the abandoned police station in Borehamwood. I've been to the abandoned school in Hatfield many times before but its just vandalized and destroyed. Me and my friends got chased by a homeless person in there too. Recently i went to the there and now security have been put in place and sit in there car and circle the area. I would recommend if you go to the Borehamwood abandoned police station as some teenagers have raves there during the night. If you could suggest me some places near hatfield,brookmans park,welwyn etc it would be much appreciated. Stay safe exploring!
