I'm thinking of getting the kids geocaching to add another layer of interest to our cruel parenting experiments family walks.
Neither DH or I have smartphones. DH has a Garmin for his running which presumably has some sort of GPS capability but I don't know how usable it would be.
Do we need more kit? Or is there another way of doing this I don't know about?
(I grew up letter boxing on Dartmoor with my Dad but I assume that's sort of died out now with the hi-tech version?)
