Update 10/18/20 I decided to make this cache easier. First I changed the name of the cache to a hint. Second, you must go to the given coordinates to start this cache! To find this cache you must solve the following puzzle.
the Sea is reversed. S.S. Itari is mixed up and blind. 12,6
Once you observe what you have to at this location, put its NAME into the checker to get the coordinates for the final.I live close by so don't be afraid to message me if you have any concerns. It also has nothing to do with the plaque on the bench.

You can validate your puzzle solution with certitude.
