We do try to practice what we preach. A good cache is worth preserving and therefore worth adopting. (All caches in a gorse bushes are good!!!) However if the cache is a traditional one and just consists of a box under a boulder it’s best to archive and free the location for a new cache. The new cache may even have some interesting information in its notice or an intriguing puzzle. In any case a new cache will encourage cachers who have already found the original to visit the place again.
Not all caches are worth preserving. We have adopted three caches and they have all been puzzles and would have taken more but they had already gone.
