There is nothing hidden at the posted coordinates. You do need to visit them, however, as they are the starting point for your nighttime adventure!
At the starting point, shine your flashlight around (I hope you brought a good one!) until you see a white reflective dot. Head toward the dot. When you get to that dot, shine around for another. Repeat. There may be a dot or two left over from a previous night cache at this location, though I tried to remove them and I even used a different route. If you get to a dot and can't go any further, backtrack to the previous one and look again. Undergrowth and branches may affect seeing the next reflector, so I suggest stepping a few feet in several directions from the dot you are at while looking for the next one if you get stuck. After navigating some pretty interesting terrain (in the dark, no less!), you will eventually get to the cache, whose location should be obvious.
After doing what you do with a cache container, you can search around for some orange reflectors, which you can use, along with your GPS, to find a much easier way back to the starting point.
