Essentially, the boundaries of Germantown are:

--Washington Lane on the north
--The R7 Chestnut Hill E tracks/Wister Ave. on the south
--Stenton Ave. on the east
--Wissahickon Ave. on the west

The northern and eastern boundaries are a bit fuzzy. Some argue that G'Town goes as far north as Upsal St. Some also argue that Johnson St. is the divider, as that divides zip codes 19144 and 19119. Mt. Airy USA says Washington Lane, as do the street banners on G'Town Ave. And I've only seen Stenton used as a boundary for G'Town once that I can recall, but it seems to me to be a natural boundary.
