Today's Location: [Sandusky (41,-82)]
The Sandusky graticule encompasses the central region of Lake Erie, creating a high probability of geohashes over water. It is recommended to use the point directly south of a water 'hash as that day's site. The Sandusky graticule also extends into Canada, albeit via Lake Erie, and contains both the most southerly part of Canada's mainland, and its most southerly island.
It also includes North Central Ohio. Most of Erie and Huron counties, as well as part of Lorain county, are in this graticule, including the cities of Amherst, Attica, Attica Junction, Avery, Avon, Avon Lake, Bay View, Bayshore, Beldon, Bellvue, Berlin Heights, Birmingham, Bismarck, Bloomingdale, Bogart, Brighton, Brownheim, Caroline, Castalia, Cedar Point, Celeryville, Centerton, Ceylon, Clarksfield, Clyde, Collins, Cooper, Crystal Rock, Danbury, Delphi, Elyria, Fitchville, Flat Rock, Florence, Greenwich, Gypsum, Hartland Station, Havana, Henrietta, Huntington, Huron, Kimball, Kipton, LaGrange, Lakeside, Litchfield, Lodi, Lorain, Marblehead, Milan, Monroeville, New Haven, New London, North Eaton, North Ridgeville, Norwalk, Nova, Oberlin, Olena, Omar, Parkertown, Pawnee, Penfield, Peru, Pittsfield, Pontiac, Port Clinton, Reedtown, Rochester, Ruggles, Sand Hill, Sandusky, Sheffield, Spencer, Standardsburg, Sullivan, Vermillon, Wakeman, Wellington, West Lodi, Weyers, Willard, Willmer (sorry if I missed anybody!).
