This cache is NOT located at the posted coordinates. This cache is located along the Reservoir Trails in Middletown close to the Black Trail. Do not attempt to search for this cache after sunset.
The actual location for the cache is a little further off the trail than I normally place them - this was a result of proximity issues.
Difficulty rating (for the puzzle and Cache) is accurate at 2.5
Solve as two separate puzzles being mindful to be sure that the overlap section is the same for both.
The final location will bring you close to an interesting spot within the Reservoir Trails lands. The path to it is not well defined so when searching for it LOOK for an asphalt path over the pipe, for the trailhead.
While searching for the place where the cache was hidden, I had the opportunity to encounter a descendent of the person who originally owned the lands (on his father's side) and the person responsible for the specific relic where you are being taken (on his mother's side). This spot is the common denominator where, like this sudoku, the two families came together.
