Come out and learn about Geocaching -- a real-world, outdoor adventure that is happening all the time in 190 countries. To play, participants use the Geocaching app and/or a GPS device to navigate to cleverly hidden containers called geocaches. McArthur Island is a geo-training playground for new geocachers with a variety of cache types and difficulty levels. Come to this and meet indoors for a brief introduction to the sport, and then we will go for a sensible walk (rain or shine). We will find some caches!
