Land-use decision

Lud is a fictional city in Stephen King's Dark Tower series and mentioned in his Rose Madder. In The Waste Lands, the book's protagonists travel from Lud to an alternate reality version of Kansas via a supersonic monorail. However, they also pass through a thinny before reaching Kansas; therefore there may be no relationship at all between the Kansas of our reality and Lud.
