This cache is part of a chain of caches that are all within about half a mile of the University Mall. There are three traditional caches each with a riddle. At each physical cache, you will find a riddle.
The answers to each riddle help you get a number to put in the lock at the bonus mystery cache. Inside the final cache are handmade keychains so all the riddles have to do with the “key” theme either in the question or the answer. Find all the caches to this series on this Bookmark list.
