I'm shocked still to find places used in The Dark Tower that are real. I have read The Road to the Dark Tower which points at one such location, but other books disecting the series might point out more I guess.

Two I know of being real are the Turtle Pocket Park and the Vacant Lot. I have seen some more that flatly creeped me out but I don't have much info on them yet so I won't post them. Anyone else find any?
