The cache is not at the published coordinates.

This is an experimental cache. Recently we heard about a new geocaching idea from U.S. cacher ChileHead called GeoMob and we thought it would be a great idea to set a cache using this new feature. If it goes well then we'll try to dream up some more inventive uses for this idea.
So, in order to find the coordinates for the cache you need to arrange for at least 5 other people to join you to launch the GeoMob web page on a mobile device while being located anywhere in the counties of Buckinghamshire, Bedfordshire or Hertfordshire (BBH) at the same time. When the 6th person joins the virtual mob then everyone will get the details for the final cache location on their device's screen. Then off you go!
There is no need to log in to or register on the GeoMob site, just open the web page and make sure your phone's location is available to the browser. In the box marked "Which mob are you attending?" enter the number 1752 and wait for more people to join. You will see the number of people in the mob increase as they join.
This cache is ideal for any Event Cache held in the BBH area, but you can use other means to gather your mob together. You don't all have to be in the same location, just somewhere in the BBH area (see map below) and viewing the web page at the same time. However, the published coordinates, close to the centre of the BBH territory, are a good place to gather for an event or a 'mob' and will put you not too far from the physical cache. There's plenty of parking and a great view from here as well.

All 'geo-mobsters' need to be inside the green circle
