I found a very nice GPS device couple of years ago in North Wales.
Owner had marked home location – lovely small village in middle of nowhere – but difficult to narrow down to which house in a little street of cottages.
Saw it was near a local church so phoned them up and said “anyone in that road keen outdoors kinda person who’s been to Wales and lost something” – priest said yes they thought who it could be and inquired and yes they had lost GPS so I posted out and got a nice Cotswold voucher in return :)
