If you are familiar with downtown Milford and know exactly where this one is, congrats! You're one step closer to the final cache. However, if you have absolutely no clue where it is but you're up on your Milford history, I have hidden a hint at the posted coordinates that should direct you to the general area.
Once you mark the location of the hydrant, subtract .101 from north and add .431 to west to get the final coordinates.
If you park downtown, all stages are within a 5-10 minute walking distance.
