Letter boxing a new creative journey

I am at a time in my life where I am craving the outdoors more than ever.  I heard Gertrude Mueller Nelson say on a iTunes video that we crave the outdoors like a vitamin! This summer I am planning on hiking as much as I can with my five year old companion! 

Letterboxes allow us to fit some creativity in too! It is a hidden treasure (hand-carved stamp and log) you bring a stamp pad, your hand carved stamp and a log of your own! You stamp in the log and "collect" their stamp in yours! 

I love the idea of a world of trails with little art treasures waiting to be found!  Pic from my log I left (I am rocking the monkey stamp), Woo hoo- how are you spreading the creative love in your world?
