Hi, I have just been approached by one of the tutors from the Engineering School at MoD Boscombe Down Amesbury. They are now using Geocaching to teach the Apprentices from the ETS about navigation skills. The first cache to be used was one of ours "In View of a Hill Fort (Durnford)". So if you see the log books signed visited by ETS you will know who they are. I am working on them to get themselves a registered name with GC.com. They will be going on another hunt very shortly. Geocaching is now part of the apprentices syllabus.
