In reading the “Ghost” novels several times, I’ve wondered if Vanderbraak Centre is near Colchester, Connecticut, in our universe.  If not, where would it be located?

Actually, the location of Vanderbraak Centre in our world is that of Plymouth, New Hampshire, the site of Plymouth State University, where I taught for several years in the early 1990s.  I obviously changed the arrangement of the town to a certain degree, but not that of the river or the bridge, or where the main streets are located, simply because in towns such as Plymouth/Vanderbraak Centre there’s usually a geographic and practical reason for their placement.  The university in the “Ghost” books is also located in the same place as Plymouth State is in our world.
