GREENFIELD — A group of 45 children and parents went on a technological treasure hunt at the Hancock County Fairgrounds Thursday as part of an introductory class in geocaching.
Geocaching is an outdoor activity that utilizes GPS devices to help participants – called geocachers – search for hidden goodies disguised to blend in with their environment.
Programmed with a geocache’s specific coordinates, GPS devices guide geocachers to the general area – usually within about 30 feet – of where a geocache is hidden.
