In his poem “One Winter Afternoon,” e.e. cummings describes Eighth Street in Greenwich Village at the “magical hour when is becomes if.” Well, it seems as though Eighth Street has reached that hour once again. The street, which once played a distinct role in Village bohemia, began as a hub for book dealers and fostered the original Whitney Museum. Eventually, the street became a district for shoe stores and edgy fashion anchored by Patricia Field. Field decamped for the Bowery about nine years ago and much of the street has since devolved into a hodgepodge of chain stores and characterless low-end retail.
