This is a mini run area designed for 2-3 level 50 characters.
To begin you should head to 'Amidst Empty Buildings' in Kansas, beat up the ghost thats there, then head east and north and attempt to take an item in that room, which spawns another ghost. Kill it and take the key it drops and return south.
Unlock east which will cause a few dead delinquents to rush you, and then head east through the prison picking the doors north and south and killing all of their contents as you go. One of the dead delinquents you kill on this floor will also have a key which will unlock the up exit in the middle of these rooms. Once you have it and have headed up, again pick doors and clear rooms.
In the central room after you go up the first time you can punch hole to scare a mutant rat into popping out.
And the room east has the prison warden.
(this needs updated a lot because I STILL dont know how to open the second up exit door, I dont have details of mob hps/xp etc, and I don't have the details about items you need to spawn the angry spirit on a second run through)
