Never heard of geocaching? Not a problem! Come to this program to learn about this growing sport and participate in it. We will provide attendees with GPS units, and then you can use them to locate hidden caches using GPS coordinates. A great way to get started with navigation and geocaching! Meet at 1 pm at the North Overlook Beach Playscape. Free; outdoor activities may be cancelled if raining or inclement weather.
