The Utrecht, Netherlands graticule is at latitude 52, longitude 5. It contains the cities of Utrecht, Amersfoort, Apeldoorn, Lelystad, Hoorn en Heerenveen. It contains the entire IJsselmeer lake, but still the largest part of this graticule consists of land.
This graticule was the first one outside the United States described at this wiki.

 Currently active
CO2 Lives near Utrecht. I have been geohashing since 2008 and am still (kinda) active as of 2014. I do not hash very often, but if anyone wants a meet-up in The Netherlands, please contact me.
Freeze_XJ is a friend of CO2's and occasional geohasher.
Georgina is visiting Eindhoven from the other side of the world, doesn't really have a good idea of the geography in the Netherlands, notes that travelling by train from Amsterdam to Eindhoven takes less time than it does to cross the city of Sydney (by car or public transport) and would love to meetup one Saturday in March 2012.
 Probably inactive
Nubilosus lives in Amersfoort, and wants to play but thinks this graticule is way too inactive.
Cascade lives next to Nubilosus and thinks the same.
Forthur lives in Ede, and thinks that as soon as we have enough people complaining about there not being people here, we can stop complaining.
GeneralDusty lives in Vleuten (near Utrecht) and thinks that Forthur has a point.
Math1985 agrees with all of the above.
Kevin lives in Driebergen and thinks that we've got enough people here complaining to stop complaining about the lack of people.
Conorach Is from Utrecht, has transportation available and would love to meet up with other people in the Utrecht graticule. However, whenever he checks the daily coordinate it ends up being somewhere on the IJsselmeer. He proposes that everyone keeps in mind the weekly meetup and tries to be there more often.
Jan Willem Lives near Amersfoort, in Bunschoten. Will try to be there on Saturday meetings if the coordinates are somewhere on land. Hope to see you soon!
