Geocaching is a world wide phenomenon that involves satellite science to hide and search for containers that contain a log and other trinkets called hitchhikers. All 36 Virginia State Parks offer Geocaching. Jared Ress, an interpreter at Pochahontas State Park, says there are a thousand geocaches within Richmond City limits.
Many people have their own GPS units, some download a geocaching app to their smart phones, and the state parks rent GPS units and there are instructors to help out.
The theme for state park caches this year is bird watching.
