I (we) maintained 7 until last weekend when we archived them all. Initially a brilliant bit of fun and very exciting for the little ones (lots of nice comments about the locations/circular walk almost every weekend)
However a local got fed up with people walking on the bridleway near their house and things got very nasty quite quickly (no details, but I will probably be looking for the details of the local ROW officer in the near future if some of the latest ‘reports’ are accurate)
Sad thing is it was actually the local ramblers doing a walk past their house that started things
EDIT – No grief from Geocachers until several were ‘destroyed’ and I was not quick enough to ‘temporarily disable’ the caches. Even then it was just gentle reminders
