Brookvale By Night
I love night caching, its one of my favourite aspects of this game. Going out with a group of friends in the dead of night and following some reflectors, or walking down a trail. This cache is just another opportunity to do so.
Start by going to the posted coordinates and finding a black tag on the bottom of a corner post of a black fence tucked behind the grass.

This tag will have 4 letters on it. Enter these letters into the below certitude for the start of the reflector trail.
You can validate your puzzle solution with
certitude.
It should be obvious what to do. It will be VERY obvious once you get to the cache. If you think "this might be where the cache is" its not. You will need a flashlight.
