I've been wanting to try Geocaching for a long time, and today I finally did. Today was just another lazy Sunday, and then on a whim I suggested to my family "Hey lets go look for hidden treasures". I picked an easy nearby cache, and after dinner I took the whole family treasure hunting. I had purchased a nice little app for my iPhone that you can use in place of a dedicated GPS unit. Furthermore it gives you direct access to over 700000 geocaches around the world which you can search through, and comment on. The app worked like a charm and we all had great fun - we'll definitely be going Geocaching again.
