About once every 25 years, it becomes possible to be in the uncertainty circle of both hashpoints simultaneously if the longitude is less than +/- 0.000100°. For now, we track the closest distance between two hashpoints.

This map shows the points we've visited. The opacity of each circle is proportional to the number of Tongs who visited the hashpoint that day. Grid squares are 0.1 degrees. You can see the counties we've visited - Cambridgeshire is in grey, and Norfolk to the northeast and Hertfordshire to the south.

== Notes and plans ==
 
−
 
 
−
* The tongs are a little late to this particular party, and often hope to meet someone at a hashpoint. Often we have a good adventure anyway.
 
−
* We'd like to try to do a hash with only a map and compass, not even using a car GPS to get us there. We later found out that this is called [[No_Batteries_Geohash|no batteries geohash]].
 
−
* M suggested a [[Birthday_Geohash|birthday expedition]] and doing a geohash on holiday.
 
−
* We'd like [[52,0|Cambridge]] to be the UK's most active graticule.
 
−
* We'd like to have some kind of recognisable tshirt or something so [[/T|T]] doesn't need to ask strangers 'Are you geohashing?'. Reflective vests work for this.
 
−
* We carry an [[/Emergency_Fun_Box|Emergency Fun Box]].
 
−
* If ever the hashpoint fell in any of our back gardens, there'd be a barbecue, and '''you're''' on the list.
 
−
* Monitor the hashpoints for northeastern France each weekend and take the Eurostar or ferry there last minute for some [http://xkcd.lapin.org/index.php?number=426 géohachage].
 
−
 
 
−
=== Things we never remember to do ===
 
−
 
 
−
* To remember to wear long trousers (and maybe wellies) when we go hashing.
 
−
* To remember to mark the GPS coordinates of the car when we leave it.
 
−
* To remember to put a working torch in the [[/Emergency_Fun_Box|Emergency Fun Box]].
 
−
* To remind ourselves that [https://en.wikipedia.org/wiki/Countryside_and_Rights_of_Way_Act_2000 The Countryside and Rights of Way Act 2000] gives the general public the conditional right to walk in certain areas of the English and Welsh countryside: principally downland, moorland, heathland and coastal land. Instead we feel usually feel very naughty and invariably later find out what we were walking on was a public footpath.
 
−
* To take the picture proving that we were at the hashpoint sufficiently close to the GPS receiver so that the viewer can actually read what it displayed upon it.
 
−
* To remember to not plan and let the day happen as aimlessly as possible. Visiting the hashpoint is hardly the ''true'' point of all this, let's be honest.
 
−
 
 
−
== Other geofun ==
 
−
 
 
−
* We once let off a [http://balloon.tongs.org.uk/ helium balloon with a message on it] and it was found 85 miles away. We couldn't contain our excitement when we got that email. We're likely to do it again with the left-over helium. We found out since buying the helium that it's not good for the environment (and nor are the balloons for that matter).
 
−
* We're sort of interested in orienteering and Ingress too, but haven't done much about it. Update: B went through an Ingress phase, got to Level 5, and is now over it. Geohashing is more fun.
 
−
* Now that it's summer, F and B have started going for walks on some Friday nights. Right now we're walking up the Cam away from Cambridge, and will start the next segment of the walk from Upware.
 
−
* <strike>Now that it's summer, we've been going wild swimming</strike>.
 
−
 
 
−
== Variants of geohashing ==
 
−
 
 
−
Tongs like playing with the idea of randomly-generated plans for fun. Here are some variants of geohashing.
 
  
−
* F suggested we could do ''decihashing'', where we just shift the decimal point across one place to give us a set of possible points within roughly a five mile square around Cambridge. We thought it might be just as fun. We later discovered that many people have also had the same thought, and even use the same name. For example, see [[Decicule]] and [[Talk:Proposed_achievements#Decicule]] and [[User:Pinecone#An_Immodest_Proposal]].

−
* [[/Hashlunch|Using the hash to decide where to go for lunch]].
 
−
* F suggested a subset of points of the local area consisting of those found on interesting National Trust properties. Projecting this set onto a unit square in the 'best' way is left as a future task. The Tongs suspect we need someone good at making patchwork quilts.
 
−
* The achievement of ''inverse geohashing'' involves computing a future hashpoint based on a hypothetical movement of the Dow Jones. To get the hash, you have to correctly predict the movement and visit the hashpoint. For a better chance of achieving this, go to as many of the hypothetical hashpoints as possible.
 
−
* The achievement of ''geosplashing'' has two possible definitions. The first is that the hashpoint is in a toilet. The second is that it is ''used'' as a toilet. The third (from [[User:Sourcerer|Sourcerer]]) is that geosplashing is jumping in puddles at the hashpoint. Some of us think the other two definitions are disgusting, but we include them here for completeness.

;January 2018:[[User:Tongs/B]] has moved to [[51,-0]]! The other Tongs remain in [[52,0]]. I wonder if this means I should set up a separate user account for myself, or optimistically hope that we all keep going geohashing together in spite of the distance...

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). If you see postings from 'Tongs', it's usually Tongs/B.

Please feel free to say hello using email, to leave a message on our answering machine, or to visit our wiki.
