This is a night cache, so it is essential you:
A) Come at night.
B) Bring a flashlight (preferably a decent one).
C) Scratch that. You might actually want a head lamp since at the final your hands will be preoccupied.
The starting location of this night mystery cache will lead you to a parking lot surrounded by trees. Many of them have glowing orange dots on them, but you are looking for the one that has MULTIPLE dots on it. This tree will lead you down the correct path.
Keep following the glowing orange dots until you spot the final guardians of the cache. Once you find the TWO guardians, they will help lead you to the final hide location. There is an unmistakable sign that T&A 137 have been there. Once you find that marker, get searching, and take note of the cache attributes...
Happy huntings!
