If you are looking to get your family outside this spring for a little exercise and fun while using their brains at the same time - give geocaching a try. Geocaching is a sport that is similar to a modern day treasure hunt. However, instead of using an old map and searching for an X, you use a GPS device, a set of coordinates and provided clues to find the booty. While you won't find a buried treasure chest heaping with gold and jewels, you and your family will find a cache of treats hidden in an eco-friendly hiding space. Sound like fun? Great, grab your kiddos and read on to discover the rules, etiquette and how to get started with your first geocaching hunt.
