To find the 'Pebble of Peril' Geocache , go to geocaching.com
The cache is located near west stow country park.
The three missing digits can be found in the video.
Clue- They're not written in a caption, or anywhere else!
P.S. geocaching.com are quite busy at the moment so are taking quite a while to list the cache... So if you'd like to find it sooner....
The co-ordinates of this geocache are N 52 19.??? E 000 38.456
Don't forget to sign the book and make a video of your find!
I posted a video response but can't see it yet. Great cache!
