Grant has gotten pretty interested in Geocaching this past year. The concept is that you use an app on your phone with GPS to locate a cache. Some of them are just canisters with a logbook that you can sign but others are containers with items inside left by others who have come along and you can leave something yourself in exchange for something from the box.
And it turns out, there are plenty very near our apartment, so he started with those. He often took Kendra with him and she was always excited to go "Treasure Hunting" with Daddy, those a couple of times we all went out together.
Right before leaving.
