The Guardian is an elaborate geocache that takes you all over the city basically…the creator of the Cache took us on a series of caches of which each provides another clue to the last stop on the cache.. The last stop is these elaborate grounds complete with ghouls and scary monsters…even in these final gardens which are on about a 2 acre area there are clues to find including the key letters and numbers to build a combination for a lock that protects the final cache.
