A night cache in the trail network around the Tarrytown lakes.
Tarrytown has a lovely network of walking trails around its lakes:
The coordinates will take you to a three-way trail junction. But which way to the cache!? You'll need a flashlight and darkness to find it!
Look for small reflective tacks in trees. When you see one, follow it! One tack means go straight. Two tacks, turn. Three tacks, you have arrived at ground zero! Look down for another three tacks that mark the hiding spot.
You will never need to leave the path. From the posted trailhead, the cache is less than a quarter mile away.
If you are afraid of the dark, you probably can do this during the day, especially with the hint.
