My 5 year old loves 'treasure hunting' as he calls it and has wanted, for a while, to have a cache of his own to maintain. It is in a residential area, stealth required though not at all a hard cache to find.
A cache for my son to maintain, fully experiencing every aspect of this fantastic hobby. The container is large enough to stash a variety of goodies!
