This cache follows the "Old Runnels Bridge", http://coord.info/GCVJE8, cache that once resided here. This time, there is a puzzle to solve to find the cache coordinates.

Good luck, and as always since this is a high muggle area, please use stealth when looking for and replacing the cache. Also please do not include spoilers about the cache location, hide, container, or how to solve the puzzle in your logs or I will delete your log so that others can fully enjoy the puzzle and cache.
I've just learned that there is a real Letter Box cache also hidden in the same area as this cache is hidden. Since Letter Boxes and Geocaches look similar sometimes, please be certain you have found the correct cache type. We should be able to coexist at this site.
Congratulations to "Bill The Cat 89l" on the FTF!
