I'm guessing it was a zombie that gave you permission to hunt the graveyard?
There is a cemetery near me that the last know "member" was buried in the late 1920's.
There is a huge grassed in section now that looks like an old parking spot, and the cemetery itself is so far out of the way, that I doubt many people even know it's there anymore.
I stumbled across it quite accidentally, and have asked some locals if they even know the name of it.
All I seem to get is "there's a cemetery there"??
I still won't dig it, but that parking area sure looks inviting!
