Like a good treasure hunt? Did you know there are treasures called geocaches likely hidden in your neighborhood as well as all around the world? Led by naturalist Debbie Nowak of 1000 Islands Nature Center, this class will show you how to get started with Gecocaching. Bring your own GPS or GPS-enabled mobile device, learn about the game, and even try finding a few practice caches around the library. A limited number of GPS units will also be on hand. All ages welcome.
