The Cedar Grove Historical Society will present the program “Historic Upper Montclair Business District” on Wednesday, March 28, at 7:30 p.m. at the Cedar Grove Library.  Helen Fallon, a member of the Board of Trustees of the Montclair History Center, will chronicle the development of the Upper Montclair Business District from a rural settlement in the 1880s to a burgeoning town in the 1930s.  Historical facts, some architectural notes, neighborhood lore and plenty of “then and now” photos are incorporated into the presentation.  A short business meeting will be held before the presentation.
