You might wonder what the checkbox that says “Include archived clues” on the Search Clues page means.
This is a way for those that are interested in viewing clues that are normally hidden. This is usually because the letterboxes are thought to be lost but may also because the boxes have been removed by the planter. The important point is that if you follow the clues, your chance of finding a letterbox are slim. Still some people like to find interesting hikes or the potential thrill of finding a box that was thought to be lost!
