Geocaching Enthusiasts Holding World Convention In Md.
HAGERSTOWN, Md. (AP) -- The GPS-based hobby known as geocaching is drawing enthusiasts to western Maryland for what organizers call their annual international convention.
The GeoWoodstock event begins Friday in Hagerstown City Park, then shifts to the Washington County Agriculture Education Center near Boonsboro for the weekend.
Organizers say they expect as many as 5,000 participants, including product vendors.
The hobby involves using GPS data to locate small, hidden boxes containing items of little value. Enthusiasts record their finds and often travel long distances to explore new courses.
The Maryland Geocaching Society developed the Washington County GeoTrail in 2013 in anticipation of the annual convention.
