Eustace Boyce and Elodie Broussard exploring the streets of La Rochelle
La Rochelle is a town in France, and the twin town of
Tackleford.  Griswald's Grammar School and a school in La Rochelle are maintaining a student exchange program.
Mimi Broussard, a citizen of this town, once quite unflatteringly described it as "a dumb" (which caused some displeasure among her class mates), but also lauded the "well maintained road out of town". 
La Rochelle may be meant to be the
real French city of the same name (both are port towns , ), but that isn't 100% certain.
Known citizens of La Rochelle: Edit Natalie Durand , former girlfriend of Ryan Beckwith.
Jean Choux-Fleur, had a crush on Natalie , but was seen by her only as "ze local simpleton". 
Elodie Broussard, her younger sister Mimi Broussard, and their parents.
Camille Duplass, Mimi's friend-turned-archenemy. 
Camille's posse, of which one girl is named Hélène.
