You are the milk production coordinator for a community consisting of five farms, represented by the five colors in the map below. Five people come to you, one from each farm, each asking for help placing their cows for maximum milk production.
These are the guidelines for maximizing milk production:
- Each farm must have exactly one cow.
- A cow can’t be next to another cow, not even diagonally.
- There must be exactly one cow in each row and each column of the farm grid.
Can you place the five cows in accordance with the placement guidelines?

Once you’ve finished, write down the “grid address” of each cow, starting with row 1, then row 2, then row 3, etc. For example, 1A2B3C…. Enter your ten numbers and letters, with no punctuation or spaces, into the Certitude checker to get the coordinates and parking info for the cache.
Final cache location is closed dusk to dawn. Approach the cache from the south.
