Looking for a fun way to exercise both mind and body? Are you bored with the same ole same ole? Why not try geocaching? Let Diane teach you a fun, interactive outdoor activity that combines hiking with a tech-aided treasure hunt. The name derives from a mashup of "geography" and "cache," and the game itself transcends territorial, political, gender and age boundaries. It's a great outdoor activity for all ages! Instead of a parchment map where X marks the spot, you use an app on a smartphone and your powers of observation. Instead of hunting for a buried chest, you're looking for a cache hidden in an eco-friendly site above ground.
