Although I'm much more likely to spend a lovely summer day with my butt glued to the chair working on a new TUAW post, I do enjoy the sport/hobby/game of geocaching. If you're not familiar with the term, geocaching is defined as "a global treasure hunting game where participants locate hidden physical containers, called geocaches, outdoors and then share their experience online." When I first started geocaching, smartphones didn't exist so I'd print out a map, grab my Garmin GPS, and head out to the field. For the last few years, there has been a boom in iPhone apps for geocaching. Here are five apps to help you enjoy finding those hidden caches.
