Saturday, August 8, all day. Never heard of Geocaching? Well, now is the time to learn. Geocaching is a sort of treasure hunt, where users use a handheld GPS device to find a hidden container, usually containing a log book and small trinkets. This phenomenon has grown to a world-wide level now available in every corner of the planet. This is your chance to experience the first geocache to be placed in a County of San Diego park. Guests must bring their own portable GPS devices and be familiar with them. This is a self guided tour with a brief introduction from Ranger Justin. Program will meet at Goodan staging area. Rain or muddy conditions cancel.
