The Philadelphia graticule is located at 39,-75. Today's location

Downtown Philadelphia is located in this graticule. However, the city is bisected by the 40th parallel and a big chunk of the city are in the Allentown, Pennsylvania graticule. Parts of the Far Northeast are in the Newark, New Jersey graticule, and many of the South Jersey suburbs are in the Atlantic City, New Jersey graticule; those may be more convenient to get to for some people, depending on the coordinates of the day.
