Factual error: In Chapter 68, Trashcan Man finds a BAR (Browning Automatic Rifle) in a guard booth outside a nuclear storage facility in mid 1990. The BAR was phased out of US military service in the mid 1950's.
Continuity mistake: In Ch. 72, Stu describes finding Harold dead, and recalls that "Harold still clutched the Permacover notebook in one stiffening hand." But earlier, in Ch. 64, Stephen King states that Harold "put the Permacover notebook into the Triumph's saddlebag" immediately before shooting himself.
