There are two ways to find this cache. The recommended way is to solve this classic cipher which gives the exact coordinates. The alternative is to find the other two Puzzle Box caches, see where they take you, then use a cacher’s intuition to locate Lisa. The cache is not far from Lisa’s spot and is probably findable, although to discover exactly how far away to look, you would have to solve the cipher of course! Whichever approach you take, you will need wellies for the retrieval. Adults may well get muddy, but children definitely will!
