The Challenging Part
The most challenging requirement of this honor is probably this:
5. As a unit, club or family find the clues and then locate at least ten letterboxes, four which can be part of a series. Individually “stamp in” your stamp, imprint the letterbox stamp in your log book and record your find on the web site.
