[Sarnia North, Ontario
The Sarnia North, Ontario graticule is at latitude 43, longitude -82.
It is comprised of about 50% water (Lake Huron), the northeast section of Michigan's thumb area (including the cities of Sandusky, Croswell and Lexington), and the extreme northern edges of Port Huron and Sarnia, Ontario. The majority of the land-mass of this graticule is farmland.
Given the low overall population density of this graticule, individuals from these areas may want to consider the Saginaw or Detroit graticules instead.
