“Kids love treasure hunting activities, especially when they actually have to get out of the house to participate in them. These days, it is possible to engage in treasure hunting activities using Global Positioning System (GPS) receivers. According to geocaching.com, geocaching is an outdoor fun activity where participants use GPS tracking devices and other route-finding techniques to hide and find objects (geocaches) at precise locations marked by coordinates in every direction. Geocaches differ in size and appearance, but the sizes of caches are usually displayed on each cache page.” (more)
