All geohashers are cordially invited to the 10th anniversary 2018 geohashing day meetup in the Cambridge UK graticule.
- 21 May 2018 (Mon): An excellent celebration of Geohashing Day will take place at 4pm local time at a place yet to be determined.
- 26 May 2018 (Sat): is Mouse Over Day and might be more convenient so the invitation applies to this day too.
A field ploughed with straw...
The Tongs is a name for a group of friends who go geohashing in the Cambridge (UK) graticule, but who might stray into the Northampton graticule sometimes. We usually aim to visit hashpoints nearish us at 4pm local time, if it looks like there's something interesting in the area or if people want to meet up (we monitor our talk page, so leave us a message if you do).
Please feel free to say hello using email.
