(Cambridge City, IN)--A water main break was affecting parts of Cambridge City Thursday.  A statement advising of the break and issuing a boil advisory went out to Cambridge City residents who live east of the river Wednesday afternoon.  The boil advisory will be in place through at least the remainder of Thursday for people in that area or who experience low pressure.  Drinking fountains at Western Wayne schools will be shut down Thursday.  Students have been told to bring water bottles.  The break forced the cancellation of extracurricular activities Wednesday.
