In combining three of my favorite activities - traveling, sketching and letterboxing - I have brought home not only a sketchbook of what I saw while traveling, but another book that is my letterboxing journal complete with photos and the clues and stamps that make letterboxing such a fun adventure. Then there's the other sketchbook - the one I call A Sketch A Day. Here's a sketch I made in Forest Park, Illinois during a visit to a cemetery.
