Today's Location:[Detroit, MI]
The Detroit graticule is at latitude 42, longitude -83. It includes about 90% of Detroit, all of Detroit's western suburbs (Southfield, Livonia, Canton), all of Oakland County (Royal Oak, Troy, Pontiac), the western part of Macomb County (Sterling Heights, Warren, Center Line) and all of Ann Arbor. It also encompasses about half of Windsor, Ontario and half of Flint, Michigan.
The Detroit graticule does not include northern Flint (43, -83), some of Detroit's eastern suburbs such as Mt. Clemens, or eastern parts of Windsor (42, -82). However, depending on the density of XKCDers and the location of the hot spot, individuals from these areas may want to consider the Detroit graticule instead.
