Chicago is not entirely in one graticule. The northern part shares a second graticule with much of the suburbs, Kenosha, and southern Milwaukee. Since this graticule is mostly Lake Michigan, it will be rare that it gets to meet. The Chicago graticule also excludes many of the suburbs. A possible solution to this problem would be using a shifted graticule divided on the half-degree lines extending from 41.5 to 42.5 degrees north and from 87.5 to 88.5 degrees west. This would be a smaller proportion lake than either of the two Chicago graticules. It would also be almost entirely contained within Illinois. The proposed area would include very nearly all of Cook County, as well as all of DuPage and Lake Counties, most of Kane, Kendall, McHenry, and Will Counties, and very small parts of Indiana and Wisconsin. This would include all the important cities of the Chicago area, including Chicago, Aurora, Elgin, Evanston, Joliet, Naperville, Schaumburg, and Waukegan. It would exclude Kenosha and Gary, but they are in other states. Also, this would separate Chicago from Milwaukee.

Another possible solution would be, in addition to the Chicago graticule, to consider the three graticules immediately to the west, northwest, and north of it, and out of those four locations, select whichever is closest to the city center (and is not underwater). This solution was first proposed by "Gylbert" on the xkcd Blag, though in relation to Calgary, not Chicago. See the [[Gylbert Algorithm]].

On days when the meeting point falls within Lake Michigan, meetings are moved horizontally and only horizontally to the nearest beach.  This allows for more reachable locations (Metra helps here) and more frequent meetups.

Likewise, on days when the hash point falls in the lake, use the hash point in the graticule directly to the west.

Notable Dates

Graticule unlocked.png
 Virgletati earned the Graticule Unlocked Achievement
by being the first to reach any hashpoint in the (41, -87) graticule, here, on 2008-05-24.

Official Meetup

In accordance with the Main Page, the official meetup of the 41,-87 graticule will be held every Saturday at 4pm Central time.

  • The first Saturday meetup (05-24-2008): Happened! But only one person showed.
  • The meetup for (06-07-2008): Four of us drove down from the city. Nice little spot right off of the road. We were a few minutes late and did not see anyone else there. Pictures were taken but they remain on a cell phone that I do not have access to.
  • The meetup for (06-21-2008): Five people total showed up at the suggested alternate location, a beach near Uptown.
  • The meetup for (07-25-2009): One person showed up. Was in a residential neighborhood in the suburbs.
  • The meetup for Feb 16, 2013: zhukant and lrbrink90 stamped their feet on a freezing sidewalk then ate Subway sandwiches in their car in Oriole Park.
  • The meetup for Dec 14, 2013: nesbiteg walked through the fresh snow to a point just off the Lakefront Trail in Uptown.
