Nyctohylophobia is the Fear of forests at night. So it only makes sence that this be a NIGHT CACHE.
The starting coords will lead you to a path. From there you will have to search the forest with a flashlight for the 2 glowing markers.
Make your way to these markers and search the forest for more markers. Continue this until you find 3 glowing markers and there you will find the cache.
To go back to your car just follow the markers back the way you came.
